If the government didn't provide public education, how would that affect opportunities for young people from different backgrounds?

They would all be vastly better off, as, instead of the State plundering their parents' hard-earned money, their family would be allowed to invest it in whatever form of education they chose, allowing the children to be sent to highly-competitive and far more prestigious and schools without any difference in the parents' finances. Citizenship would take a quantum leap upward in a single generation.

So many families come from all over the world to America to get a better education so they can do better with their future and to make a better income. if this opportunity went away, all the hard working people and kids will not be able to afford it and I feel like our economy would go down also.

It could cause more chaos due to none of them knowing the risks and everything in the real world and it could lead to more homelessness because they can't get a job from no education.

It would cause everyone go down the same career path and too many workers in one department that any other.
