I think the education is very important for every citizen, but I believe there are people that really has to earn a college or something, instead there are citizens who have more conveniences, so if given the payment of school free for all, would be a useless expense, and yet many people would not study for lack of economic resources. Besides the government would not have a very favorable economic status for the country, having to give everything free.
I therefore believe that the government help citizens including immigrants with low incomes to get a free college tuition.
