For me, two points:
(dating myself here) Minimum wage used to be $5.75 when I was in high school. I worked my ass off for an entire summer. I fuckin hated it, but we all gotta hustle. Around my last shift, I came out to the parking lot, and someone had done my car dirty with a hit'n'run. No note, no CCTV, nothing. The damage was in the neighborhood of $2k, which is exactly everything I had saved up that summer.
I worked my ass off 300 hours to break even. It might as well just have been some community service work release program. Fuck capitalism.
The other is when I was older, post-grad. I had a shitty job where I had to pony up for own health insurance plan with high deductibles. I started having random tingling in my joints, so I did the responsible thing and had it checked out. I got sent to several specialists who ran a battery of tests. I'm already in the hole, $3k out of pocket, and all I got was, "We're not sure what's wrong."
The tingling lingered, and I started looking up information for myself on alternative, holistic sites. Someone had listed similar symptoms and said it was just a vitamin deficiency. That couldn't be it, right? Well I ordered some supplements, and within a month, the tingling was gone.
$3k down the hole. Fuck capitalism.
Graduating from university and working full time under capitalism. They don't even try to hide that you're there to be make as much money as possible, while being paid as little as possible. They use every possible loophole to pay you less and even if they didn't you still couldn't afford to get by. I live in the greater vancouver area where rent is insanely high, to the point where I can only afford to live on the other side of the city from where I work. I lose a total of 2 hours a day to my commute, to go to a job that I slowly ruin and destroy my body/hearing, to make a wage so low that I will never be able to retire, so my company's owner can make literal millions. This is all deliberate in it's design. I hate it. I'm miserable, most of my friends are miserable, and anyone not at the top of society is miserable. I just want everyone to have a better life but some asshole born into wealth wants to own my life
