Tariffs and bans are policies of fear. They happen when we are scared that another country’s innovation has surpassed our own.
The best response to competition? Investing in your own science, technology, and education. That’s true courage.
Jhooper@luckytran Bans should really only be used for products that are directly dangerous. Any other reason I can come up with is out of ignorance.
