because you would want the united states as a entity to be a prosperous place if you kicked out the mexicans you wouldnt want the white people to have no money they have to beg with a sign on the street you would want to give them some maybe trivial stuff to do like cleaning up trash  so they can operate to make the place better overall and not have vagrants  and it makes the rich people safer too when the people are well taken care of
