Why do so many children in Mexico walk across the border to attend American schools everyday?

Why? The bullets aren't as thick on this side as they are in Mexico.I'm sorry i don't buy your bleeding heart ramblings about those poor mexican children.We've got children in the same shape over on this side.Over crowded class rooms.Teachers that shouldn't be teaching.Very little money to run our schools.etc.We need to solve our problems first,then we can look at the people who want their children to receive a free education on our borders.If you have the education to teach I bet mexico would love to have you come over and teach.Take a bullet proof vest with you if you decide to go.
