Well, the kind of long distance running that some people do for fun would definitely kill me

Pour rappel, chaque grand parent peut donner plus de 30 000€ à chacun de ses petits enfants sans que ça soit taxé, il y a déjà de quoi pas mal les gâter !

Sure, a tax dodger might end up going through the garbage to remove the transactions corresponding to receipts that were thrown away from their records, but that’s at least quite a bit of effort. I don't know where you live, but in france the government doesn't check the garbage to find the receipt for simple groceries

Customer can still get a receipt, it just won't always be printed, you'll have to ask. So this wont change anything related to tax evasion, it just means that you won't have a garbage can full of newly printed receipt next to the exit door

This internet version of centrism that everyone hates on is bizarre to me, for the reasons you say - the “only commit half a genocide” type of centrism. Are there people who really strike a middle ground on every issue on principle?

That's not a principle, it's just a rhetoric. Like when people demonstrated in Charlottesville : one side wanted to get rid of a slavers statue while the other side run a car through the crowd. Then Trump took a "centrist" position and said that there was some very fine people on both side, which was just a way to defend his side

They have private companies and a market economy, how is that a communist economy exactly ?

If your only argument for saying they're communist is because they said so, then you must also believe that north korea is a democracy right ?

I've been looking at this for 30 minutes expecting to see james bond
