I'm surprised to read such an absurdly simplistic idea from such a celebrated "smart man". Note how he glosses over, entirely, any possible unintended (yet certainly foreseeable) impacts on the economy, infrastructure, culture, and societal stability -- somehow a slowly recovering (and still weak) economy will make any concerns moot. And, what kind of immigrants? Any? Really cheap labor forces that will drive down wages? Mediocre talent? Maybe just anybody? If he wants to make a proposal like this, he should elaborate a bit. It reads like a late night "brain fart". Overall, it sounds like he's all for anything to make _his_ generations' retirement easy...too bad for the generations to follow.
