Some of the jobs may just move overseas...
Let's face it, there will always be pressure to reduce the cost for lower skill jobs. If the US closes their door, jobs will move to other countries. India is a few time-zones away, but maybe it'll be an opportunity for Mexico or Canada to start operating the IT departments for US companies with those highly motivated immigrants.
You might not like it, but those kids from poor countries also want their slice of the pie and they are willing to move across the world to get it.
