What decent paying job can someone do right now with a high school degree and no experience other than restaurants?

Jobs are for the losers of capitalism. The vast majority of them don’t pay shit.

If you want money, you gotta either find a niche to be self employed in or find a way to exploit the labor of others. Working hard as an employee is a terrible plan. Ask any sweatshop worker in the world where a lifetime of that has gotten them.
