Liberalism is unsustainable. When things go wrong in liberalism they pile more liberalism on top. Pretty good example of what's wrong with the US budget, US healthcare. Liberalism breaks it. Government breaks it. They pile more liberalism on top of it until it eventually implodes, like Obamacare is going to, or like Social Security is going to. All of these things, they're not sustainable, because liberalism isn't.
