I own a small business and his tariffs would fuck me right up.  I buy my my materials from a US supplier and manufacture my products in the United States, but my supplier gets those materials from Mexico. If he jacks the price of that shit up my entire business model gets worked pretty hard.  

Most of my customers buy modified parts from me to use with things that are manufactured in China.  If he slaps that 60% tariff on that like he's talking about, my customers are going to be buying less of those and as a result buying less of the stuff that I make.  

I'd probably go out of business.

One of my friend owns a store and probably 90% of the things he sells in there are manufactured in China. There is no us equivalent.  Jack, those prices 60% and he's gone under for sure.

Hell, you jack those up 20% and he's probably fucked.

It's also terrifying because every business in my field does extensive business in one way or another with foreign countries, so if he gets in and does this shit it's not even like I can close my business and fall back on a job within my industry, because the whole thing is going to be suffering.
