Megan McArdle says her bit on Trump. She is fairly intellectually honest, for a mouthpiece of the business wing of the system. I’m sure she would like to avoid addressing the concerns of the unwashed, but Trump is too big to ignore.
Immigrants are good for the economy, and no politician can do anything anyway, so shut up, she says in summary. She’s a little more polite, and less theatrically exasperated than most journalists addressing this subject, but the message is the same.
Trump is a populist eruption of the kind we see in times of social stress, like George Wallace or Ross Perot. Nothing will come of it, but it is a sign things are not going well, and there is some risk of losing control.
