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.
