Interesting addendum to Matthew Feeney's observations and thoughts on Switzerland's anti-immigration referendum from earlier today, via Bryan Caplan:
Swiss anti-immigration voting was highest in the places with the least immigrants! This is no fluke. In the U.S., anti-immigration sentiment is highest in the states with the least immigration - even if you assume that 100% of immigrants are pro-immigration.
.....The main hurdle to further immigration is insufficient immigration. If countries could just get over the hump of status quo bias, anti-immigration attitudes would become as socially unacceptable as domestic racism...
