If you pay the same amount each month for your mortgage for 25 years and inflation is 2% each year the last payment should be half as valuable as the first (edit: about two thirds, actually. Maths!), so you’re encouraged to buy on credit.

But this is only meaningful if your income is also going up, right? Otherwise you're still getting fucked by inflation. You're paying the same percentage of your income towards that mortgage but all your other expenses are going up.

The idea that a little inflation is better than none comes from the thought that money should be changing hands as much as possible, and if money kept its value people would be incentivized to save all their money and keep it to themselves, and that would remove it from the economy. But if the value of that cash goes away people will want to invest it in something that might not lose its value, like a service.

Idk that's just the way it's always been explained around me I'm not some money jockey

to prevent all money from ending up in a single party’s hands.

Inflation encourages and amplifies wealth accumulation.

to prevent all money from ending up in a single party’s hands.

I beg to differ.

Example: suppose you own property, gold, a business, or something else with tangible value. When inflation causes cash to decrease in value, your assets are safe. They have intrinsic value.

Example: suppose you're living a lifestyle where you can't afford assets like that. Maybe even living paycheck to paycheck. You make the same money, and you can buy less with each paycheck. You can't start buying assets when money keeps getting tighter.

I think it's pretty simple to see inflation only hurts the have-nots, while others are protected by the value of their accumulated assets.

Throughout the 1800s, the us saw increasingly more severe and more frequent economic boom and bust cycles. This helps the wealthy as they are the ones who can buy up all the assets during the busts, and the common man gets fucked. This all culminated with the great depression. Its something like 20 recessions of 15% or more retractions between and 1930.

When the fed was given teeth to actually control the fractional reserve system., we've seen constant inflation, but the number and severity of economic recessions has gone way down.

We've seen 1 retraction over 15% since 1940. And that was because of COVID lockdowns.

This small, controlled inflation is great for the regular joe because it creates stability. And it was all going well until deregulation during the 80s.

Yes, not all demand is the same, but the idea isn't to increase the demand of bread, it's to increase investment. If sitting on cash gets you more interest from the bank you're going to let it sit more. If it loses value you're going to spend or invest it more. And yeah, this does happen, among other things because inflation affects everybody, not just consumers, although this also influences how likely individual people are to buy things on credit. Companies and governments also care about this.

As always with economics things aren't straightforward, and you get lots of weird paradoxical behaviors, but the big lines of this one are easy to see. If you have some inflation and low interest rates you're gonna be more likely to make big purchases or investments on credit. And the real problem is once you have those and are paying them back if inflation flips and suddenly the 100 bucks you pay each month for that credit go up in value to 110 you may find yourself losing money on that investment or being unable to afford it, which is a big problem when that happens to literally everybody who owes money (including the government) all at once.

And since the people you owe money to are mostly just a handful of banks.... well, that's not a great wealth redistribution technique, is it?

I hear this very often, but has this ever been proven?

Yes, multiple times we've seen this play out in real life. The most recent big one would be Japan 1990s. Look up "The Lost Decade". The biggest one in the USA was the Great Depression in the 1930s.

People are not exactly going to stop eating or paying rent which already eats more than half of people’s income.

You stop buying all but the absolute basics (bulk beans and rice and nothing else?), so all the food that isn't a "basic" goes un-bought and the people producing that food/product lose their jobs. Then you stop buying food when you're out of money, which is what can happen in an extreme deflationary environment because you have no income, because you lost your job, because no one buys whatever your work produces.

And if you stop paying rent, you're going to get evicted. If you stop paying your mortgage, the bank will take your home. This played out exactly this way during the Great Depression.

I could see gambling and entertainment become more stale, but I’m not sure how big of a problem this is.

Its much more than just those sectors, but just imagine how many jobs are in the gambling and entertainment business. Now all of THOSE people are out of work competing with you for whatever jobs remain. That, too, happened during the Great Depression.

It’s funny that people always talk about inflation vs deflation and never mention what would happen with a fixed price for everything

Its mentioned pretty early when learning economic theory, and its disastrous, which is why it isn't suggested as a policy to put into place, though from time to time some governments do, and its, as expected, disastrous.

Lets imagine you're a livestock farmer and there is a fixed price for two types of meat you produce: Beef and Frogs. In our theoretical country of FakeLand, we use the SuperCoin (SC) currency I just made up.

• It costs you 5 Supercoins (SC) to produce a unit of beef, an the fixed price of beef is 10 Supercoins (SC).
• It costs you 4 SC to produce a unit of frog, and the fixed price of frog is 8 SC.
• You produce equal amounts of beef and frog on your farm.

Now, you (and most people) like eating beef and very few people like frog. So the start of the Year 1 opens and your beef sales are VERY busy, and you're selling just a tiny tiny big of frog. If this keeps up, you're going to be out of beef very quickly, and you're going have LOTS of spoiled frog meat. In a normal economy, you would reduce the cost of frog from 8 SC, to possibly 5 SC making it half the cost of beef, so you could clear out your inventory of frog before it goes bad, BUT YOU CAN'T IN FAKELAND, because the prices are fixed! So for Year 1, nearly all your frog meat goes unsold and spoils and you lose 4 SC for every unit of frog you didn't sell. You sold all your beef, but with your losses on frog meat, you're near poverty because you essentially only earned 1 SC when you sold a unit of beef because you had to cover the losts of 4 SC for a unit of unsold frog meat.

So next year, you learn your lesson, right! Less frog meat, and more beef!

Year 2

• It costs you 5 Supercoins to produce a unit of beef, an the fixed price of beef is 10 Supercoins.
• It costs you 4 SC to produce a unit of frog, and the fixed price of frog is 8 SC.
• You plan produce 10 of beef and for every 1 of frog on your farm.

You still can't do anything with the prices you sell for, because Fakeland sets the fixed prices.

So you're all ready to make tons of SC on beef, except there is a disease that wipes out 90% of everyone's herds before it goes to market. In a normal economy supply and demand would make the cost of beef rise to maybe 20 SC or 30 SC to recognize the scarcity of beef, but here in Fakeland the prices are fixed.

In the first month of Year 2 selling, you sell out of beef lightning quick because beef is still relatively cheap at only 10SC! Because of the shortage of beef, people also willing to buy your frog meat. Since you only made 1/10th of that this year, you don't have that much of it either. In a normal economy supply and demand would let you raise prices on frog too way above 8SC to maybe 10 SC or 12 SC to help you cover your beef losses, but in Fakeland prices are fixed, so you can't. You sell out of frog in the first month too.

So, you now have another 10 months or so with nothing to sell. Further, you have money, but there's no food to buy from anyone because it all sold cheaply from fixed prices.

This is how government setting fixed prices on things that the cost and popularity vary on can play out. If you want to see real life recent examples. Here's where the Venezuelan government in 2020 fixed prices on foods and how disastrous it was.

Mostly because that's impossible. Ideally you want small inflation so it's a bad idea to just leave money around, but either way 0% inflation is about as impossible as 0.4999% inflation.

No wonder the degrowth movement exists. It’s because of this bullshit that we harm everything around us.

Economists and those that made political theory have been looking for better alternatives since the formation of civilization.

What is your suggestion for a better system?

Honestly? Sometimes my brain just runs with stuff like this. Having travelled enough, it gets really fascinating, what's expensive where and why. A universal value metric would be about as useful to me as the Kelvin scale is. It's nice to have it as a thought tool, but it's not particularly useful day-to-day.
