Does McCain understand "free-market capitalism"?

TAMPA, Fla. - Republican presidential candidate John McCain says Wall Street's financial turmoil is the result of unchecked corporate greed.

Yes, and the Pope is Catholic.
... and a bear does shit in the woods.

What does John McCain think fuels his cherished free market? If not greed, then what???

... and, for what it's worth, what exactly has McCain in mind when he says this:

"I have spoken out against the excess of corporate executives, and I can assure you that if I am president, we're not going to tolerate that anymore. In my administration, we're going to hold people on Wall Street responsible."

Is he proposing the U.S. Government sit on every corporate board in America?
