> America has a much higher risk tolerance than the rest of the world.

America is one of the most risk averse countries in the world, seriously. Americans are constantly scared - of loosing job, of physical injury, of everything and everywhere.

> Failing is considered a good thing in the USA

America punishes failure pretty hard. Some peoples failures are ignored, but most peoples failures are punished in pretty significant ways.

Yes, only a tiny minority of palatable failures is allowed in the US. For everything else, society will discard you like rubbish.
