For the uneducated, unproductive, unskilled, hopeless and homeless person of tomorrow will prey on the educated, productive, skilled person who has what the poor person wants. So no one wins. There are some very direct inverse correlation's between the educational level of a society and the crime rate. The more the population is educated the less they turn to crime. So it helps everyone to see that tomorrow's youth are educated well and properly.
Many nations offer free guaranteed education through college.
A basic tenant of education, I think, is that when the process fails, it is the fault of the teacher, or the school, or the system, but it is NOT the fault of the student. When you explain something to someone, anything, to anyone, it is up to you to explain it so that they understand. If you do not use words they comprehend, then you, not they, have failed. Their only obligation is to inform you when they do not understand what you are saying. Then you must find other words.
