It seems implausible to me that Trump could be elected. (Of course, it seemed implausible to me that he could be the nominee-apparent, and there he is.)
There is a great ambiguity in tech employment. On the one hand there are the H1Bs who are designing chips at (let's say) Intel or MIPS, and who have genuinely rare tech skills. On the other hand, there are the H1Bs who are doing basic CRUD or such work, and whose skills are not rare at all--it's just possible to pay them a bit less and control them more than the local talent. Do you really think that the replacements at Disney all graduated at the top of their class from IIT or ETH?
