The supercommittee was a superdud — and we should be glad. Nonetheless, at some point we’ll have to rein in budget deficits. And when we do, here’s a thought: How about making increased revenue an important part of the deal?

And I don’t just mean a return to Clinton-era tax rates. Why should 1990s taxes be considered the outer limit of revenue collection? Think about it: The long-run budget outlook has darkened, which means that some hard choices must be made. Why should those choices only involve spending cuts? Why not also push some taxes above their levels in the 1990s?
