> people making significantly above the market financial trading are commonly seen as negative-value producers when most do generate a significant amount of positive value

They generate a significant amount of money - not value, money. They concentrate wealth in the hands of those who can afford to pay them to do it, a process which begets itself. That's why traders are commonly seen as negative-value producers by society as a whole - they contribute to decreased social equality.

Your argument here is circular - financial traders can only be said to be generating value if you assume that money and value are in some way equivalent. The former doesn't prove the latter.

As for nurses - if they're so easily replaced, why are so many rich societies dependent on immigrant health workers? And I'm sure you're not telling me that, if you were dying, you'd rather be attended by a stockbroker? Or could it be that "value" is a nebulous concept that is highly situational and varies from person to person?

Capitalism is very successful in certain arenas but it doesn't universally improve quality of life, and if you want an example then look no further than healthcare, and consider the difference between the US and any country with a nationalised healthcare system.
