Stock is easy to goose back up via QE and/or lower prime rate. Once you lock in those interest rates on debt, though, there's nothing you can do about them. You're also ignoring trade barriers that other countries have, and the fact that we've been offshoring manufacturing capacity for over three decades. What Trump is doing today is what Bernie was advocating in the 00's.
Interest rates are lowered when inflation is low. Inflation is low when supply is high. Tariffs cause supply shortages. Inflation expectations are up. Interest rates will be up.
You're crazy if you think that the trade barriers are over _thirty percent globally_.
Net FDI = trade deficit is an accounting identity. Reshoring and the trade deficit aren't necessarily complementary.
