Read about American history pre-1920. It was brutal. This was a land of settlers, not immigrants, for a very long time. Settlers had high casualty rates and were forced to fend for themselves with no stable established industrial/agricultural grid. They were equivalent to Europeans in like 2000 BC.
There is no "luck", it's pretty obvious system factors actually. No one is "luckily" surmounting them right now even as they decline. Despite everything America marches onward and has left its home continent in the dust.
