Subject: Re: Mark Cuban Says: Let's Play Trump Jeopardy
Without looking up the nitty-gritty details, I believe the US tried once before to use tariffs to generate significant revenue. The Hawley-Smoot (sp?) tariff bill from the -I think- 1930s. From my dusty memory of history, it didn't work and the US continued to wallow in the Depression.

I have always thought of them as either a form of sanction, or to provide domestic companies a leg-up, by increasing the prices of foreign goods, thereby making domestic goods more attractive, which in turn raises sales of domestic goods.
