The Great Depression was started by a Businessman come politician who imposed massive tariffs back in the early 30's named Herbert Hoover. Heard of him?
And didn’t reduce other taxes to compensate for the load on the economy.
Turns out that it was all bubble and the load burst it.
You do remember that the first 100 years of this country, the federal government was financed almost entirely from tariffs?
Tariffs in United States history have played important roles in trade policy, political debates and the nation’s economic history. The main goal of the tariff was money to pay the federal budget.[citation needed] Controversy arose over whether manufacturing interests were favored and consumer interests hurt by high tariffs. The 1st United States Congress, wanting a straightforward tax that was not too onerous and easy to collect, passed the Tariff Act of 1789. Treasury agents collected the tariff before goods could be landed, and what became the Coast Guard prevented smuggling. Tariffs were the largest (approaching 95% at times) source of federal revenue until the Federal income tax began after 1913. For well over a century the federal government was largely financed by tariffs averaging about 20% on foreign imports.

That is Milton Friedman's opinion Not everyone agrees that Smoot was the reason, after all the Country managed practically on import duties alone.
Read contemporary accounts and histories of the Great Depression written by the people that actually lived through it and they tell us what really caused the GD and it wasn't an obscure trade act that affected just 4% of the economy. SmootHawley is a contemporaneity rewrite of history to fit the Free Traitor™ religious dogma.

The economic Boom Bust cycles of which the Great Depression was one were caused by the Central Bank. Which is why Jackson fought them for most of his Presidency to eliminate. We had a stable prosperous economy for a long time after that until the PRIVATE Federal reserve was created (Central bank 2). Look at what laws were put in place to prevent another occurrence of the great depression such as Glass Seagall Act that Clinton repealed leading to the bust we had back then.
