All of America's prosperity came about because everyone else was destroyed after WW2 plus the US had a huge manufacturing base at the time. Now all of those once destroyed countries have recovered plus the US has zero manufacturing base since it has all been outsourced to various different countries.

The United States is cooked and it shows with the new alliance between China, Russia, and India. America can't compete because it has nothing to use to compete with since it is a full service economy that produces nothing physical of value.
