I agree, mostly (we'll eventually use robots to relieve drudgery -- chimp and gorilla slaves not economical or politically correct).
I've always thought that US immigration should be actively encouraged for anyone with an advanced degree (or any degree in sciences) from an accreditted univerisity. We need the innovators, scientists, engineers, & entreprenuers that will create these jobs.
People say that XX number of years from now, social security burden will be unsupportable. Unless we really screw up, this is unlikely. 50 years from now people will be encouraged to "retire" at an earlier age & all will be encouraged to get even more education. Increases in productivity & automation will allow and even mandate it.
