McKinley
Least favourite: Led the way for the highest tariff in American history, McKinley Tariff. Also, allowed big business to monopolise and drive up consumer prices.
I'm glad to see a Republican complain about these kinds of things.
I generally support anti-trust legislation and small tariffs on imported goods, if any tariff at all, in order to promote competition and keep consumer prices low. The only reason I support any tariff at all is to encourage consumers to buy American and support American workers. Big business will make their profits. Competition keeps prices low.
