Tariffs = bad, see https://en.m.wikipedia.org/wiki/Smoot–Hawley_Tariff_Act

1 Business lobbies to get oppressive tariffs promising it will spur innovation

2 Tariff passes, business market value rises because of reduced competition

3 Business stops innovating because there is no foreign competition

4 Business shares stagnate without innovative product line because there is little need to innovate

5 Business lobbies for higher tariffs, repeat from step 2

It can be argued that tariffs are little more than Pyrrhic victories for the industries involved that hold back the nation as a whole and create a downward spiral
