> Attempts to browbeat the world out of "is" and into "ought" have been universal failures
There are so many examples (a single one of which disproves your "universal" claim) of idealists bring "is" more into alignment with "ought" that it would be almost impertinent to even begin enumerating them. Here's a small handful: Civil Rights movement, Women's Suffrage, and (from an economic perspective, since that what you seem to insist can never be touched by notions of "ought") the rise of Organized Labor, which made it possible for former wage slaves to earn a decent living wage.
If Hayek and Rand make you feel better about the fact that most of us over-earn relative to the "virtue" of our labors, fine. But IMHO it is best to be honest about the inequities and fortuitous circumstances which make our success possible.
