Moving right along, there is a racist element to it, but it is more nativist than racist, and more a manifestation of economic fear than nativist. In some fields of endeavor, the latter fear has some empirical justification, in the short run, and for those slaving away, the short run matters when it comes to economics.
The key here is to try to defuse rather than infuse. The latter is a cul-de-sac.
And there you have it.
How long did it take you to write that post?
