Implemented or not, Trump's 25% tariff threat is challenging the auto industry

[Botany]

6. I met an autoworker from the Detroit area who lives in Michigan and worked for Chrysler 1/2 the time in Michigan ....

... and 1/2 the time in Ontario as per needs of the auto plants. He told me that he had Canadian friends
who worked both sides all the time. The value of the cross border trade between Metro Detroit and the
Windsor Area is in the billions per year not counting the paychecks and he told me that on both sides they
have all kinds of high quality tool and dye shops to meet the needs of the auto industries too. Say a Ford
plant in Michigan needs some kind of fabricated part and they order it from a shop in Windsor now are they
going to pay 25% more for that "widget?"

I think Trump is doing this to crash both economies.
