If you study the actual practice (not what the politicians tell you) of controlling immigration from Mexico, it has always been just a lot of scare tactics on the Mexicans (as to the danger of getting swindled, robbed, raped, and murdered on the Mexican side, AND caught and deported in the US), and then almost like every 10 year amnesty is given to the ones that make it here. You will have to conclude as I did. It's a farce! They have no intention of stopping the Mexicans from coming here.That is THE POINT.
As an aside, I doubt that Mexicans have taken more than 2% of the good jobs, versus the 98% of the good jobs that were sent overseas. I don't see the popaganda minstry (the media) or the sheep that follow the propaganda slant, complaining about that. All that is left is low paying service jobs, like McDonald's and Walmart, not because of Mexicans, but because of government regulations that are not applied against overseas manufacturers (read unfair competition), that sent US manufacturers away, or put them out of business. Greedy trade unions that finally chased business away. and greedy aberrant capitalists with only loyalty for profit. In short, the “global economy” became more important than helping your neighborhood. Now there are Chinese living a tad better (getting 3 meals a day), while our neighborhood is full of welfare recipients and potential future criminals just trying to find a dignified job. THE JOBS ARE GONE to the world.
Your ignorance is incredible, construction, machine shops, manufacturing, processing plants, city and county government, road work, Americans have been pushed out of all.
It is extremely difficult to find "good jobs" that Mexican immigration has not taken over, restaurants, drywalling, brick laying, concrete work, roofing, electrical, increasingly carpentry and plumbing, and the quality of those fields declined as the Mexicans took them over.
