'A Protectionist Moment?'

Paul Krugman:

A Protectionist Moment?: ... if Sanders were to make it to the White House, he would find it very hard to do anything much about globalization — not because it’s technically or economically impossible, but because the moment he looked into actually tearing up existing trade agreements the diplomatic, foreign-policy costs would be overwhelmingly obvious. ...

But it’s also true that much of the elite defense of globalization is basically dishonest: false claims of inevitability, scare tactics (protectionism causes depressions!), vastly exaggerated claims for the benefits of trade liberalization and the costs of protection, hand-waving away the large distributional effects that are what standard models actually predict. I hope, by the way, that I haven’t done any of that...

Furthermore, as Mark Kleiman sagely observes, the conventional case for trade liberalization relies on the assertion that the government could redistribute income to ensure that everyone wins — but we now have an ideology utterly opposed to such redistribution in full control of one party, and with blocking power against anything but a minor move in that direction by the other.

So the elite case for ever-freer trade is largely a scam, which voters probably sense even if they don’t know exactly what form it’s taking.

Ripping up the trade agreements we already have would, again, be a mess, and I would say that Sanders is engaged in a bit of a scam himself in even hinting that he could do such a thing. Trump might actually do it, but only as part of a reign of destruction on many fronts.

But it is fair to say that the case for more trade agreements — including TPP, which hasn’t happened yet — is very, very weak. And if a progressive makes it to the White House, she should devote no political capital whatsoever to such things.
