It's because people don't understand that if you make it difficult to pay software developers who may be citizens of a different country $80000 to work in the US, companies can just as easily outsource to those same software developers, in their own countries, but instead pay them $20/hr instead. Essentially, America was able to use its mythology as a land of opportunity and equality to convert $20/hr being sent elsewhere to getting 20 somethings to move to the US after their home country took up all the burden of paying for them being raised through their childhood and subsidizing their education and pay them to stay in the US and spend money there (and get a good chance of creating a billion dollar startup in the US instead of their home country as well). Much like most decisions Americans have been making lately, the push to de emphasize immigration is pretty much all downsides for the US, for little to no return, other than "we stuck it to them!"
