What is so bad about Mexico and Central America that makes their people want to escape to the U.S.?

They come here for a few reasons: Our government and Mexico's government have told them to come here for the American dream for a long time now. Illegals know before they come here about all the free benefits they can get: Free welfare for all their kids, free education, free medical care at government medical centers, food banks, unemployment benefits, tax return money, better prisons, money for government housing programs, citizenship for their kids born here. They are not trying to help our country, they are helping themselves...take, take, take. Why is all this happening? Globalism.
