Hang on and you will become well informed on how they suck away at our wealth by providing slave wage labor.
By people like trump.
If you are in competition for a job with an illegal immigrant it is likely you have no skill or education and need to gain more employable qualifications.. (not that immigrants couldn't hold better jobs but they normally try under the table because of their status- at restaurants or farms)
They use Hospital Emergency Rooms as Primary Physicians.
They use our schools, forcing the hiring of Bi-Lingual teachers and forcing foreign language compliance.
They live several families to an apartment/house and produce an excessive amount of garbage forcing an increase in Property Taxes.
The work in construction putting plumbers, electricians, carpenters, stone cutters; I guess only these losers suffer.
