Free trade allows Americans to live a higher standard of living. All the goods we buy from foreign countries are cheaper which lets us spend our money on additional things.

Americans even in the middle are so much richer than even our "rich world" peers they don't even realize it.

If the UK was a state, it would be poorer than.. Mississippi on a per-capita income basis.

Note UK itself is incredibly unequal, so if you remove London from the UK the per-capita is far far worse than Mississippi.

Now thats before we even get into our continental friends like France, Spain, Italy, etc.
