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.
I'm a restaurant worker.
My dad had terminal cancer. It was almost certainly his last Christmas. I wanted to spend it with him, but was scheduled to work. I talked to the AGM, who said, "We should be able to handle that. Email me to remind me." So I did - got the out of office auto-reply. Emailed the GM. Never heard back.
Worked up my courage, pulled all his doctors' notes together, approached the other AGM. Launched into my spiel: "So, my dad has cancer, I brought --"
"If it's about your schedule, I can't help you."
He's dead now.
