By that measuring stick, you must have a really bad opinion of the USA because they are what they are from conquering most of their territories and exterminating its native population, and that was done yesterday. The biggest country in the World, Russia did that expansion in 1500, and Germany wanted to replicate the Americans in WWII. Is the prosperity of the US independent from having a virgin country with bast resources and no population? Certainly it is not, (North)Americans could have a big number of children to replace the exterminated native population and exploit its bast resources and automate everything because there were few workers to do the job. In other places of the world automation was more expensive(China, India) than just using workers, so it did not happen. Population skyrocketing meant a healthy young population and economy to prosper. People got rich killing buffaloes or cutting down millennial forrest or gold(that had been extracted and depleted on other parts of the world for milenia) and not to talk about Industry being financed by(very expensive at the time) sugar and cotton cultivated by slaves in the South.
