When I started to look at that, I was sort of intellectually shocked. Contagion is the critical phenomenon which causes the thing to fall apart.

Protectionism will do little to create jobs and if foreigners retaliate, we will surely lose jobs.

At the risk of some oversimplification, if the skill composition of our work force meshed fully with the needs of our increasingly complex capital-stock, wage-skill differentials would be stable, and the percentage changes in wage rates would be the same for all job grades.
