The strongest point in our history in terms of innovation and trade was when we had a strong middle class. Independent innovators had the capital to try out ideas and start their own companies. The middle class has shrank over time, and money has shifted to a few ultra-wealthy. When you're trying to put food on the table, it's impossible to get the time and resources together to innovate.
The best trade policy is to close tax loopholes for the very rich. Raise taxes on the rich while decreasing taxes on the middle class, increase funding for universities and grants for innovation.
