Larry, I don’t think that David Brooks is suggesting that supply-side policies be forever abandoned. (He supported making the 2001 tax cuts more supply-side.) And in this very column, he signals his support for various policies to expand the new investor class.

In NR, I outlined a tax reform that would cut marginal tax rates on investment and on income, help families, and raise as much money as the current system. Common ground?

Incidentally, the tax reform was originally the idea of Robert Stein of First Trust Advisors. He couldn’t take credit for it at the time I started writing about it. My only contribution was to recognize a good idea when I saw one, and devise some arguments in its favor.
