Dude... "make yourself valuable" is not a constructive suggestion. A person flipping burgers IS providing value for their employer because their employer sells those burgers for profit. If a company needs people to perform labor for profit, no matter how menial or unskilled you think that labor is, they should pay those people a fair wage.

And no, fast food is not "meant to be a career". But that's not an excuse to exploit the labor of the people who take those jobs. Especially not when corporate profits are through the roof.

I have personally worked in jobs that facilitated millions of dollars in profits for my companies, and not a single one of them paid an actual living wage. The funny thing is that those jobs also tended to be a lot easier and require less actual skill than the customer service jobs I'd had.

Then you have my early boomer dad. One of his first jobs was pumping gas and washing cars at a gas station. That's not "skilled labor" nor is it "supposed to be a career". He was still paid well enough he could afford his first apartment.

But what other economic system would be the alternative if not communism?
