Well, in a nut shell, two things. The government did not enforce the law and when it didn’t the Housing Industry opted to make a quick buck instead of demanding that the government enforce the law.
There already were laws that prohibited hiring illegal aliens. These laws were enacted in order to protect the jobs of the American people. That is supposed to be the main interest of the government, but it is obvious that the main interest of the government is how much those who run the government can benefit by what the government does, or does not do.
When one company in any local job market hired illegal aliens the others in the same field of endeavor had two choices. One was to monitor the hiring practices of the rouge business and demand that the government enforce the law. The other choice was to copy the rouge businesses illegal practice.
It was obvious that they could get away with it because the government was not doing its sworn duty, and it was just as obvious that there was a quick buck in it. No one thought any farther than that, so no one realized that if American workers lost their jobs there would be no buyers for their houses.
The illegal workers were sending as much of their wages as they could to their home in Mexico, because that is where they intended to return to. They were not going to buy a house here and those who might have bought a house here no longer could (No job, you know).
Anyway the immigration problem is solving its self. The Housing Industry can not sell a house, so it can no longer afford to build them. If no houses are being built there are no more jobs, even for illegal workers. If there are no jobs most of the illegals will return home as that is where they always planed to go anyway. Maybe they can be hired to put wheels on all those houses, so they can take them to their own country; where all the money went.
Well, that is not the entire problem the North American Foolish Trade Act and the Most Favored Nation (over our own) are the main problems, but no one is doing anything about any of the problems. I mean no body, not the News Media, not the Government, not the economists,
By the way, I see that the Ford Motor Company made a profit last quarter, by selling cars in other countrys. WELL DUH.
