Really, farm labor
Moving is not easy UNLESS you'll make more over there. Ever relocated for a better job?
Now, those Tech visas are temporary, right? Why would anyone hire temps, with all the lost training that will ensue? Because they are...cheaper. No retirement, long term health benefits, et other costs. Truth is, the American Corp. does not want U.S. workers.
Word I get is we should be O.K. with those terms of employment, yes? To bring Mr. Gates back to #1?
Farm labor sends billions back home every year. Want to chance a guess how much Tech labor does?
