Social liberalism is the standard Democratic Party line - different from market, classic, or neo-liberalism of the free-market types.
Okay, so now let me make my fundamental contention: Capitalism is killing us, but that doesn't mean it's doomed to fail. Global warming, financial instability, student debt, the price of education, offshoring, imperialism, the security state, and so on... these things show that we're going down a path of increased human and environmental suffering. But is it therefore not theoretically possible for capitalism to be saved? No, not at all. Denmarkian social democracy serves just that role - to allow capitalism to alter its course, by providing legislative authority over class conflicts. Does this mean we should trust legislators to be effective? No. It takes immense coordinating power that a beaurecracy is unsuited for. And the very idea of getting to the point where it exists is a difficult task.
So what I'm saying is that we shouldn't simply count on some glorious disintegration - we need to be prepared to organize en masse during smaller crises.
