NO ONE - can accurately predict the economic future in the short term - its chaotic like the weather.

But the biggest indicator of economic health is demographics - and the US wins in this category hands down compared to other developed countries.

While Japan, Germany and other countries are rapidly aging - the united states continues to be culturally very open and meritocratic.

Britain tried being "open" but it backfired in a big way.

The United States will continue to dominate - its biggest rivals are of'course China and India. China is facing a huge demographic cliff while India even though it has the demographic advantage does not have the energy reserves nor is able to fully get rid of structural corruption ( US too has corruption but everything is relative )

At the end of the day - growth is just an anomaly - the longest state of the universe is decay.
