Education Should be Free

In my opinion when the education free everybody will able to get it .I see some people have a good mentality but they do not have money to buy for education .WE can not demolition this person because the money .I am always wondering why the education in the university not free ?The government can get money from the tax from many ways but not from  education.Education is the first a step to all kind of job if is it free the government will be proud about her people.
