Is Ayn Rand Relevant?

From WSJ Online, Yaron Brook writes:

Why do we accept the budget-busting costs of a welfare state? Because it implements the moral ideal of self-sacrifice to the needy. Why do so few protest the endless regulatory burdens placed on businessmen? Because businessmen are pursuing their self-interest, which we have been taught is dangerous and immoral. Why did the government go on a crusade to promote "affordable housing," which meant forcing banks to make loans to unqualified home buyers? Because we believe people need to be homeowners, whether or not they can afford to pay for houses.
