Capitalism has lifted BILLIONS out of poverty. Hard stop.
Work is miserable for you because you are a whiny snowflake. Hard stop.
As for your alleged evil boss, capitalism affords you FAR more ways to deal with that than communism/socialism/marxism/etcism EVER would. Under your fairy tale system, THE STATE tells you what to do, AND YOU LIKE IT, whether you do or not. That, or you do your work in a gulag somewhere, or worse.
There are SERIOUS laws in place to protect anyone trying to unionize, laws that are stacked HEAVILY against an employer. If you were 1/10th as smart as you think you are, you would know that you need to contact a union and have them help you with this. They will most certainly stand between you and your eeeeevil boss, assuming that you are a large enough group to make it financially worth the union's efforts. Unions are first and foremost, businesses, and they really do not care about the little guy.
Of course, in a wide open job market, you could just find a new job. I wonder what could be keeping you from leaving such a horrible job? Could it be . . . MONEY???!! So you can buy you some of that nasty, yet very tasty capitalism!
And why would ANY landlord not lease to a paying customer? Obviously, there is something you aren't telling me.
You seem to think that capitalism is the source of all your woes- it is not. Rather, it is the source of everything you find enjoyable in life. No, the source of all your woes is first, YOU, and secondly, other people. Here's a clue, rock star- socialism is run by . . . wait for it . . . OTHER PEOPLE, who are no less greedy than the worst of the worst of capitalists.
What I hear you really saying is that you don't like to work, and you don't want to be bothered by the effort to find another job, because you don't want to work in the first place. Sorry, that's the way it goes, unless you can get you one of those worthless gub'mint jobs where people do nothing but hassle other people. Kind of like your evil boss does . . . see the pattern?
