> The greed that people talk about when they say that greed is good (by way of Wall Street, the 1987 movie) is, though.

Thing is, you can't reduce the pursuit of self interest to accumulating wealth. Therefore, even if we accept the definition of greed as merely pursuing wealth, we misunderstand Smith's quote and fail to acknowledge many sources of creativity. By disproportionately rewarding greed and not other work incentives, we build a society for the few that are driven by it, at the expense of most, and ultimately, we cannot thrive.
