How the US is rich and powerful?

How did the United States become one of the wealthiest nations in the world despite being a relatively young country compared to Europe and Asia?

The Americans are a very lucky people. They're bordered to the north and south by weak neighbors and to the east and west by fish.

America is blessed by its geography. The fact that America is blessed by rich and fertile geography yet protected by its geography has influenced US development as a great power much faster than other countries.

The US was shielded by an ocean and a weak and friendly neighbor bordering it; the US adversaries were on the other side of the globe, i.e., Iran, China, and Russia.

This was in contrast with Europe and Asia, as the countries in these parts of the world were now highly growing due to the lack of major conflict in their areas after the Second World War and peaked after the Cold War.

Still, before that, these countries had to deal with strong and threatened neighbors who led to destructive wars that destroyed their wealth and prevented them from growing in the same ways as the US.

The US doesn't have to face the threat of Canada and Mexico becoming so threatening to the US mainland and invading the lower 48 states. 

Throughout history, the Chinese and Koreans had to face growing Japan, the English had to face growing France, France had to face growing Germans, the Germans had to face growing Russians, India had to face the Pakistan and so on. 

Wars happened, killed millions, and destroyed the livelihood of that country, and it takes time to recover.

Meanwhile, with its secure geography and rich natural resources, America could sit an ocean away, build its military, and wage a war that doesn't impact its homeland and dominate the world, making it the wealthiest.
