Hoover was a flaming progressive and he raised top marginal income tax rates to 60% which likely had at least as much or more negative effect on the economy than import tariff hikes.
This is true and I can infer from your comment that Tariff's are progressive policy like the confiscatory marginal tax rates?
I think if you talk rationally to most people they do not have a problem the Broad Term of Trade. Specifically, they do not like production moving oversees and exported back to the US. For example, nobody should have an issue with FORD producing a 4 cyl diesel engine in Mexico for the Mexican Market; they have a problem with FORD Fusion being made in Mexico and shipped back to the US.
However, the solution is not to address the symptoms, but to cure the problem. It is true that FORD enjoys cheaper labor in Mexico than the well above market UNION labor brought on by forced gov't coercion. The progressive will defend this action saying Union labor protects the superior craftsmanship of the US worker over his Mexican counterpart. Unfortunately, the fact is that FORD quality and service records on cars produced in Mexico out performed cars built in Michigan. So not only is labor rates in the US corrupt, it under performs. This is normally the case when the government grants monopoly power to companies or labor unions.
Correct our broker UNION labor and jobs will come back. Slap a tariff and the consumer is taxed to support Govt/Union cronyism.
