It would leave the wealthier poorer and the rest of America richer. Mass immigration only benefits the people who own everything because it drives the cost of goods up and the cost of labor down. That is why they do it,!there is money and power for those on top because they are essentially stealing our country away and selling it for a dime on the dollar.

Housing would surely get cheaper for the average working American.

Exactly. The benefits accrue to a handful of labor-intensive businesses, while the costs are spread across the entire taxpayer base. So the illegal-employers milk the taxpayers for profit.

Illegal immigration would become a lot less attractive if heavy fines were imposed on businesses that knowingly employed illegal aliens, or failed to exercise reasonable diligence in identifying employees as such. The money from the fines could go to offset the cost of enforcement, or to reimburse facilities that are stuck providing welfare services for these criminals.
