If by "we" you mean US popular culture, yes. It's not universal, and definitely varies by country.

In the UK we don't tend to idolise the rich so much. Not to say it doesn't happen, but in popular culture positive depictions tend to be limited to period portrayals of idealised aristocracy (and even then it's rarely shown as heroic), with contemporary wealth usually treated as a dubious virtue.

Yes. Good point. This is a pretty US specific cultural phenomenon.

Probably rooted in the 'self made man', 'rugged individualism'. Go West to make your fortune. We forget the US is pretty young, and still has a lot of culture based on colonizing the west, taming the wilderness to find your riches.
