Some improvement, yes!

A large number of the working class Illegal Aliens have returned to Mexico and this has definitely reduced the number of people being killed by drunken drivers in head-on collisions.

However, the criminal element remains as they were never dependent on employment for an income source and pulling jail time in the US is far superior to that in Mexico.

So maybe we should require the foreign aid we give to Mexico be used to house their citizens charged with crimes here in the US.

That should even the playing field, no?
