The Washington Examiner's Tim Carney takes up the question at the Atlantic, and I think you'll find his conclusions quite fascinating.
Voters despise government officials who get in bed with corporations. But what about corporations who cozy up to government? Are companies who use cronyism to grow their profit acting unethically?
The question makes some free-marketeers uneasy. After all, we not only tolerate the fierce pursuit of profit, but also we defend it against taxes and heavy-handed regulation. Milton Friedman famously said, "The social responsibility of business is to increase its profits."
But in the age of crony capitalism, libertarians must declare that some means of pursuing profit are immoral and call on executives to reject them. This would create a positive case for capitalism -- arguing that the pursuit of profit, in the context of fair and open competition, helps the whole society. The new corporate social responsibility, redefined for libertarians, must stand athwart crony corporatism yelling "stop."
