Mollenkopf's comparison of immigrants in New York and Amsterdam is difficul
t to test, given the impressionistic nature of his evidence. Evidence point
s to differences in the character of immigrant absorption in the two cities
, without necessarily indicating the superiority of one over the other. Ams
terdam's immigrants function in an assimilationist rather than a multi-cult
ural environment; they benefit from higher levels of welfare spending and a
more equal income distribution; New York's immigrants are less subject to
discrimination based on religion. Comparing central cities rather than metr
opolitan areas may underestimate the success of New York's foreign-born. It
is problematic whether African Americans or immigrants constitute the more
appropriate comparison group. If the former, then the case for New York's
greater tolerance becomes much harder to make.
