The reason they’re not is because the fiscal long-game mostly favors liberals. To see this, let’s fast forward a decade or two and imagine a similar negotiation. I suspect that, if anything, Medicare and Social Security will be even more popular than they are today given the aging of the population, making them even harder to cut. It’s possible that raising taxes on the affluent will be less popular—some 60 percent supported Obama’s desire to do that in last month’s exit polls—but I doubt it. Historically, Americans have been sympathetic to the idea. And while it’s true that, as conservatives point out, you can’t fund the entire welfare state by raising taxes on the wealthy, it’s not the only source of revenue that’s likely to exist. If nothing else, I’d guess a future Democratic president could raise taxes on income well below $250,000—probably down to $100,000—without incurring major blowback.
