If you can't compete with a barefoot Chinese farm worker who just moved to the city, I don't think tariffs will help you.
Chinese companies bringing in H1B’s for $1.50 an hour might have a little something to do with this.
Why wouldn't they? It's very simple. You raise the tariff. The barefoot chinese worker loses his job, an American gains one. Yes the product cost more now, but Americans are employed and can now afford to buy the produce, where before they were unemployed and couldn't even afford the cheap product.
