To become an economic in the world. the US can do two most
important things:
- Research and development.: US has insane amount of capital both
physical and human. Using that the US can invent things that no
other nations in the world can. Producing better and more efficient
goods or maybe a technological interruption will increase the
demand for the US goods in the market and benefit them.
- Trade: With research and development the US have goods and they
need a market, having a lot of free trade agreement will allow the
US to sell those goods in the market and benefit from sales, It
will also benefit from them buying cheaper goods in the market from
imports and having a larger purchasing power.
