I've never trusted Deirdre McCloskey on economics: for one thing, Sinclair Davidson and Steve Kates think she's pretty good, so there's a warning sign there.
But I reckon this piece in Reason, about how economists who have started to worry a lot about automation and unemployment are wrong, pretty much confirms she's a lightweight. There's really no serious argument put forward, and she just falls back on her general theme about how free market capitalism and technological advance has been historically great, and (by implication) nothing's ever going to change. Oh, and unionists are bad.
Count me as unconvinced.
