Or they will just use illegal/informal wiring services. You seem to be very stupid but the Mexicans that "took your jarb!" are not.

Another challenge with tracking the scope of money sent overseas is that while most remittances are thought to be sent through formal channels such as banks, credit unions, and wire and postal services that are regulated by the federal government, some is transferred using informal services, without oversight.
One of these unregulated systems, known as hawala, has been the subject of recent attention in the media because of its use by people fleeing war-torn Middle East countries for Europe.
Hawala enables users to transfer money from one point to another without either side having a bank account, thus leaving no paper trail and operating outside the law.

In one of its reports, released this month, the GAO speculated that imposing a fine on remittances against people without legal status could encourage them to send money home using unregulated services such as hawala rather than going through traditional methods.
People using the informal services could not be subjected to the fines because there’s no way to enforce them.
So if more people choose to remit using unenforced systems, the revenue generated from the fines would be minimal, the GAO predicts.
In addition, the GAO reports that it’s difficult to know how many migrants use regulated methods to transfer money home, and how many go around them, so limited information exists about the immigration status of those who are currently remitting.
