PS: Assuming growth is good, Mr. Robb, rate of growth is a critical variable. Grow too fast and the character of society changes. Things always change here — that’s one of our great strengths — but it’s important that the rate of immigration not exceed (or not by too much) the rate of acculturation. Otherwise you risk ‘booooooming’ economic growth at the potential expense of cultural and political values — like democracy, free speech, etc — which are also critical contributors to US prosperity.
