Economic value however is not meaningless. It represents a measure of contribution to the capital engine that powers our lives. The whole system however is completely unfair and biased since the actual economic value created by workers is not realized by them. Workers create value that companies could not survive without but these companies do not then redistribute gains from that value in commensurate with the work done.
As such I don't have a problem with us looking at being able to generate economic value as meaningful, I have a problem with the skewed system that distributes the rewards and opportunities unfairly.
