Justin Wolfers(@JustinWolfers):The tariff math is the easy part: prices rise.⁣ ⁣ The bigger cost is trust. Michigan's auto industry works because Canadian parts makers built their future around Detroit. Threaten that relationship long enough, and they start building their next factory near a port instead, ready to sell to Europe.⁣ ⁣ That's not a price shock. That's a permanent loss of preeminence.
