Lastly, a big problem I have with the current visa situation is that it creates a market distortion by bringing in hundreds of thousands or engineers/programmers while leaving other fields completely protected. Imagine if the united states banned all foreign grown lemons but allowed in all foreign grown avocados. Well, you could say that by removing all tarrifs from avocados, we've increased free trade. But you can bet that any farm outside the US hoping to access our market that can shift production to avocados will do so, and any farm in the us that can shift to lemons will do so as well.

This is what we've done to engineering. If you make it easy to come to the US as a programmer, but not as a lawyer, you distort the market. You should absolutely expect this to deter americans from engineering and encourage them to go into law.
