The article doesn't even make sense! He's actually arguing that low wages are better than zero wages, while low wages are also better than high wages, and that the wealth creation whose impact he boasts about isn't even having a subsantial impact!
> First of all, even if we could assure the workers in Third World export industries of higher wages and better working conditions, this would do nothing for the peasants, day laborers, scavengers, and so on who make up the bulk of these countries' populations. At best, forcing developing countries to adhere to our labor standards would create a privileged labor aristocracy, leaving the poor majority no better off.
He doesn't even think to consider that, for example, a tax+entitlements scheme, that every civilized nation has, could stave off this "labor aristocracy". Nor does he explain why a Western labor aristoracy is OK, but an Eastern labor aristocracy is not.
The article is thin logically-bankrupt apologetics.
Krugman himself has walked back his old claims, he calls it "hyper-globalization" (~5minute mark). https://www.ubs.com/microsites/nobel-perspectives/en/paul-kr...
