Note that when you're poor your surroundings are usually also poor. So even if you are young and not yet burdened by health care costs and maybe even have free/good education you might need to drop out or at least spend a lot of your time and money to take care for your relatives.

Only when everybody you care about has a stable health/housing/food/(work) situation you get a chance to do something for yourself. Only if people around you are privileged enough to they have time to invest in you. You can start to build wealth. I don't mean with investing money. Maybe just by

- Lending you their garage - Allowing you to work without income for a few months - Taking care of your kids while you work a few times a week - etc...

TDLR: if all you and your surrounding is doing is directly aimed at surviving you cannot build wealth.
