If this were about Americans losing jobs to latinos
Then the solution is to pass a law that companies hiring undocumented people had to pay them the standard legal wage... And make the penalties for not doing so extremely harsh.
This would stop the exploitation of these people, and documented Americans could have a chance of getting these jobs and be paid a decent wage.
This is NOT about jobs- it is about bigotry and hatred... it is about Trump clinging to the base of his support- the bigots that voted for him, and the morons that repeatedly insisted that his statements and actions as a candidate somehow weren't racist.
