To the people saying: "I don't support the idea of free education for poor people."

That's a weird chain of thought. I think not investing in free education costs your society more in the form of welfare expenses and problems that arise more frequently in poverty (health issues, crime, etc).

While actually investing in education gives people a greater chance to be part of the economy and repay the investment by paying their taxes, having a better state of mind thus taking better care of theirselves.

Ofcourse you can lead the horse to water but can't force it to drink; if students are not properly stimulated and encouraged from home out to make an effort in class and study then the nurturing aspect of the parents have failed greatly, not the education system.

Does America have any instutions that follow up and guide vulnerable families?
