Nearly everyone I know in college (who wasn't a tech or a business major) had to pound the pavement, eat dirt, and figure out some way to just survive after that 4 year "grace period" they were granted after moving out of their parents house.
Many of them went through no end of sometimes degrading, sometimes grueling and outright hazardous jobs -- from waitressing to bike messengering, to construction jobs with mafia-run and/or otherwise dubious contracting outfits, to public school teaching, to sex work. They all talked no end shit (nearly always justified) about their bosses, their sleazy clients, their lousy health insurance, the banks, governmental agencies they had to partially or wholly rely on for some period of time.
But the thing is -- no one ever thought of complaining to these sleazeballs they were working for to say, "hey, why aren't you doing enough for me?" If anything, their attitude was completely the opposite -- instead it was: "Yeah, this sucks, the game is rigged, everybody knows, etc. Man, I need to figure something out."
And eventually, they all did. Whether it was finding non-profit that wasn't secretly capitalistic and exploitive, a public high school that was actually cool to work for, or just learning enough tech skills to get a decent entry-level support job... they all found something. Not because they were lucky, or even simply because they were relentlessly persistent... but ultimately, because they realized it was all up to them.
But thinking that the random person you happen to be slaving away for at the moment -- that they somehow "owe" you more than what they're giving oyou, or that it's they who are holding you back -- that kind of thinking, and more to the point, the refusal to believe in one's own agency and potential -- is far more detrimental and toxic to one's progress than a crummy salary, the outrageous rent, or that long, expensive commute.
