Out and out: that sucks. I'm really sorry. You deserve better.

I have a couple thoughts, some of which are probably conflicting but I'm also just reading this from the sidelines.

1. To some degree I empathize with your parents: they were born into this death cult and they probably believe in it. It's fucked up but most of us (I assume) come from Western-loving households who think hard work, grit, and eating stew makes you a better person.
2. I struggled hard in my 20s and my divorced parents were unable to help me. I ended up doing a bunch of shit that I absolutely hated (which later led me to despise myself), including joining gangs and engaging in street violence, and then eventually joining the military (thank god I never saw combat), and then bouncing around doing the most inane shit to make ends meet. Had there been some nest egg either of my parents were sitting on, I would be beyond pissed.
3. However... My dad eventually moved in with me for his latter years leading up to his death. Something I never planned on since I really didn't care for him, and quite frankly I didn't care if he lived or died (until I was actually faced with that decision). His moving in is probably the singular event that pushed me from SocDem-status to "bring on the revolution." So thinking about that, if there was ever a time in my life I would have fallen to my knees and accepted Jesus into my soul, it would have been to find out there was some sort of nest egg his broke-dick ass was sitting on that could have helped me, and him, in our darkest hour.

I know that's probably not very helpful in your current circumstances. My best advice is to do your best to have a good circle of friends who share in your frustration and struggle, and who genuinely care about you. Your mom is probably doing what's best given the environment she comes from.
