>>If wages rise here too high, Gates, Zuckerberg, et al. will merely relocate abroad while expecting the American taxpayer to protect them.<<
No, if wage rates for certain skills rise faster than other wages, that rise will signal to young people that they should take college and/or technical courses aimed at those particular skills. The education cycle is short and within a few years there would be a modest surplus of people trained with those skills. Then the cycle would repeat.
This is what used to happen years ago in engineering. The best time to start an engineering degree was when wages were low because in the five years it took to get the degree, the low wages would have reduced the number of students going into engineering and you would graduate into a hot job market.
When the government gets involved by tweaking the number of visas available in any particular industry, all that does is mess with the natural cycle of things. It also prevents wages from rising enough to attract new entrants into the field domestically.
We should limit legal immigration, and we shouldn’t necessarily emphasize skilled labor when deciding whom to allow to immigrate. If there really are jobs for which there are no takers because of the nature of the work, those are the jobs we should seek to fill with green card holders. This is especially true of highly seasonal work where it’s often unrealistic to find good help on a strictly temporary basis.
We need a 10 year moratorium and all legal immigration.
After 10 years we can reevaluate our needs. Enough!
At this point in our history, anyone seeking or supporting an effort to continue this never ending conga-line of foreign nationals/immigrants into our country, should not be trusted.
