> You’d have to tariff fruits and vegetables like crazy to make the American varieties more expensive than oceanic shipped produce.

Bullshit. I already see in the supermarket (Canadian Superstore) oranges from South Africa, lemons from Morocco, broccoli from Mexico, mangoes from Malaysia, fish from the Philippines, coconut from Vietnam, kiwis from Italy, etc.

Yes, oceanic shipping adds to the cost. But most of those countries already have cheaper labor, and that partially offsets the extra cost.
