Cowen's really illustrating how the upper-middle-class elite will fight savagely for their interests, regardless of what it means for their principles. Affordable housing is good _except for us_, high taxes are good _except for us_, immigration is good _except for us_, diversity is good _except for us_.
I particularly can't get over his outright xenophobia at the end: "Keep the dirty foreigners out, but I still hate Trump!" He can't have it both ways; either live with immigration and learn how to make it work well (which is probably the better idea), or allow everyone else to be raging xenophobes just like he is.
