Those will not be a career path for much longer.

Child labor got outlawed long ago, which is one of the reasons a lot of countries have mandatory education. High school is about much more than learning programming language or marketable skills, that's what you have secondary education for. Social interaction and other related skills are one of the big take-aways from regular school that are hard to replicate, also, that big bad world will still be out there when your children reach adult age and they then won't be prepared to interface with that.

Maybe consider moving to a place where schools are not useless, filthy, full of drugs and gangs if you really wish to solve this. And if the high schools are full of filth, drugs and gangs today what guarantees do you have that the community college won't be the same?

(And if the community college can keep it's grounds clean today, why can't the highschools?)
