> everything America needs to succeed and grow can be found right here in America
This is clearly not true. If you look around you, much of what you own, use, etc. comes from other countries, including the ideas, science, and technology behind them. Just off the top of my head, in one industry: The web, Linux ... why would we think for a moment that Americans have superior ideas to everyone else?
Also, if the U.S. doesn't buy goods, services, labor, etc. from other countries, then they won't buy them from the U.S. The U.S. is only 5% of the world's population and maybe 20% of the world's market (due to the wealth of its citizens). A U.S. 'Brexit' from the world would be an economic disaster.
