I often don’t agree with him and I don’t with all here.
But this is an excellent piece:
Adding up the effects of the much-maligned trade agreements
The relative decline in employment in manufacturing since World War II is the biggest structural change, or evolution, to hit the American economy over the past half-century. Politicians, with their preference for truthiness over the facts, attribute roughly all the 22 percentage point decline since 1971 in the manufacturing employment share to NAFTA, to China’s entry into the WTO, and to a few other scattered “corporately backed unfettered free trade agreements.” But — I really would like to drive this home — the worrisome part from trade is not the decline in the manufacturing job share from 30 percent to 12.2 percent, but the “excess” decline from 12.2 percent to 8.6 percent. That worrisome part of the decline of the manufacturing job share is, roughly, only one-sixth of the total decline: 3.6 percentage points. And the amount of decline attributable to the two big bad trade agreements is only one-tenth of that: 0.36 percentage points.
In sum, we can attribute a mere one-tenth of the excess reduction relative to Germany in the manufacturing job share to NAFTA and to China joining the WTO.
