I'll just keep saying it, the problem with undocumented workers taking jobs away from documented workers/citizens...can be substantially reduced pretty easily.
Simply start throwing the book...at those people who hire them.
Put enough business owners and high-level exec's in jail, then sit back and see how darned fast a better effort is made...in who is employed.
Of course, there will be the inevitable whining and screeching from seeing prices significantly rise on a plethora of products and services...but that's fine with me too.
The nasty little truth is, that we as a country are also to blame because of the pressure we put on companies...to keep their prices low.
Then the
'law of unintended consequences'...starts to kick in.
When the prices for domestically produced products becomes too high, then corporations who are driven by shareholders who want their returns maximized and right now, will simply go wherever they need to reduce their overhead costs...with labor usually being at the top.
