I personally work 2 full time jobs, I'm aware how scarce free time can get. I'm certainly not saying that everyone can do it on their own either. Just that cost is a very weak barrier to knowledge and that I agree you need to learn your way out of poverty.
I'm also a big proponent of basic income exactly for the reasons above, but I think the core idea is well founded. Hard work at a job (or two jobs) doesn't usually get you out of a shitty job, where as learning enough to get a better job does.
