I don't get why the only solution is to trust others to take care of you.
Society is built around people "taking care" of you in different ways. Like being a doctor, a teacher, an employer, the police, etc.
That's why we grew out of being caveman, because we're built to be cooperative with each other in our DNA. If we didn't, we'd either be small tribes or individuals and probably die out really fast. It's because we need others to rely on or we'd literally be extinct.
Please learn about run-on sentences, that shit is hard to read lol.
