This needs to be repeated often. If you want to stop illegal immigration, arrest those who employ illegals. A few business owners spending the night in jail, being charged with felonies, and facing huge legal fees and fines will have a large chilling effect. If there are no under the table tax free jobs to be had, the flow of migrants will diminish quite a bit.

Here's a thought: make those who employ illegals liable for back taxes and back wages at US minimum wage. That will hurt.

Or is that already the case? If it is the law is not being enforced at all.
