Heavily tax all wire and other transfers of money from illegal aliens to their homelands.

Here's a great idea sent to me by a listener...

If Mexico is getting $20 billion a year from illegal aliens in the U.S., seize about 30% of it. Call it a fine. If you can show that the money was earned here illegally there would be absolutely nothing wrong with taking a bit of it when it is sent back to Mexico to shore up Vicente. Look ... if you drive by a car and solicit a prostitute the cops can confiscate your car. You were using that car in the commission of a crime, it can be taken. If you sell illegal drugs the government can confiscate the money you earned selling those drugs ... and the government can do it under asset forfeiture laws without even proving that you were guilty of a crime. All they need is a reason to believe that you committed a crime. If, in fact, you earned that money legally you can sue the government to get your money back. Same rule for illegal aliens. Confiscate their cash. Take their paychecks. That is money earned during the commission of a crime. If they can prove they earned it legally, let them have it back. This would be a lot of money that could be spent on border and immigration control.
