FYI, the Feds have caused skyrocketing costs of doing business here and that’s why business is fleeing. Some good starting places to fix our GDP problem are:
1) lower taxes to individuals and eliminate the phony “business” tax which is simply hidden tax on the consumer in the form of higher prices.
2) nuke unconstitutional federal minimum wage - artificially high labor costs are killer of jobs and send companies elsewhere
3) kill the sheer tonnage of dead-end, useless, and costly regulations and nuke the unconstitutional Administrative State along with it.
4) repeal unconstitutional federal protection of unions a major reason for making Detroit a ghost town.
Tariffs on the other hand are an exercise in futility and do nothing to address these very real causes of the migration of business and industry and the flattening of our GDP.
I have never endorsed the idea of tariffs, however, I can say through real life experience that the tariffs that other countries have placed on US products hurt those manufacturers. Unless you buckle under and actually build a manufacturing plant in those countries, you are forced to accept the barrier.
Truly free trade would benefit the US greatly.
