Yeah! That's why Martin Shkrelli was so admired as a national hero in the U.S.
...right?
I can't think of a single place on this planet where greed is admired, unless you want to over-generalize and lump in general capitalism and entrepreneurship -- but I think that the effort to over-define greed into any and all wealth accumulation is missing the actual point behind the concept of greed itself.
Greed is not perceived as negatively in the U.S. as in, for example, Japan, but it is not, here or anywhere I am aware of, perceived "in a good light". When you want to suck up to an executive in the U.S., you don't commend them on how "greedy" they are, because (in the U.S. like anywhere else), that's an insult.
But cut-throat monopolistic market domination, gaming, and consumer/employee abuse - that's just sound business ethics.
America definitely worships actions that many would consider to fall under the "greed" term, even if you don't. A great example is that Donald Trump's main qualification for being President was his wealth and business acumen. I think half the country would consider him a poster child for "greed" while the other half think his actions fit in on a resume.
