Greenspan and his handler’s policies are the reason the *world’s* economy is in such a mess. (actually, they made the mess to take our savings)
I don’t think anyone should take his word on immigration.
The only reason to allow in more foreign workers is to drive down wages. You can hardly expect most american’s to support that position. If we had a labor shortage, instead of 10% or more unemployment..then there would be some reason.
Right now the US has an excess of unskilled, uneducated workers(and none workers). What we need is more capital to employ them.
