And the latino illegal aliens have a crime rate LOWER than the general population (there were
links quoted here in the last 2 months about that topic) and they work very hard,
without many of the services that legal residents get.

Additionally they pay taxes of various types even when they work in the underground economy. Utility, sales, transportation taxes, etc.

In sum, undocumented workers (people cannot be 'illegal'; behavior is illegal) are a significant benefit to the U.S. economy and to employers both large and small.

No doubt they do impact the job market and the availability of better paying jobs with benefits, but so did slavery and child workers. Employers are the perpetrators and undocumented workers are the victims.

Trump construction projects and hotels have always employed undocumented workers.
