Here is my take on it:
1) Like Israel, build a wall along the entire Mexican border using labor from the enormous prison system.
2) Second, employ the Minutemen (pay them) to be an auxiliary force to the border patrol.
3) Give the border patrol more authority and funding to expedite the process of deportation and the halt of illegal immigration.
4) Begin the ever encompassing task of rounding up the illegals that are already here; start with the businesses that employ them.
5) Finally, again use our vast prison labor system to tackle the agricultural task of picking the fruits and vegetables and also maintaining county, state, and federal roads and other such things.
It will not be easy for our country, especially the well-to-do to adjust to the fact that the cheap laborers will no longer be here.
Something has to be done....
