The FWD.us oligarchs would like to bring in foreign tech workers who, in addition to decreasing the cost of the labor they utilize by increasing its supply by their mere presence, are also less demanding and more pliable than their native counterparts are. The oligarchs would also, presumably, like us to trust them and their companies such as Facebook, since so much of their business models rely on users freely sharing information with said companies.
Sadly, the oligarchs face a problem. While the US is still a relatively high trust society--its oligarchs especially so--the countries sending the bulk of new immigrants here are not. It comes as little surprise, then, in answering the GSS question "Generally speaking, would you say that most people can be trusted or that you can't be too careful in life?", 34.6% of native-born respondents answered in the affirmative compared to only 24.0% of those who are foreign-born. (Okay, it's not much of a problem--the oligarchs don't care about rising mistrust or increasing social isolation; if you're going to hole up indoors, might as well check out your facebook feed!)
A corollary to diversity as distrust is diversity as a muzzle on free speech. Steve recently pointed to an article in the NYT about censoring trashy politically incorrect campus publications that features the perspectives of multiple "Mexican-American" students.
How does the wider Hispanic 'community' feel? The percentages of respondents, by race, who say racists should be permitted to express their beliefs publicly:
White -- 63.5%
Black -- 53.7%
Asian -- 52.3%
Hispanic -- 47.1%
