Are illegals really a burden to the host country?

Yes they are because they do not pay for the benefits they receive. They undercut wages so many legal people are out of a job. They give false information and skip on bills. Their children get free educations and legal children get programs cut to pay for the illegals language teachers. I could go on and on but that is the gist of it. Also I cannot rob a bank for a better life and get away with it so why should they be allowed to rob this country and get away with it?
