I'm thankful my mom raised us with a no-debt-mentality, and that my father was always complaining about the debt he had (he got a bad deal at a bank, and will likely be paying of his debt until he dies). I built everything with what I had, which honestly was quite a bit thanks to a previous efforts and some luck.
As soon as debt falls, the whole economic system falls. Debt is just another currency, a shadow-currency so to speak, used not to buy goods, but good-will and favors. And the best part is - you don't even have to spend it. The one that owns the debt can ask many favors, and the debt is still there.
It would be great to see the RoW unite on that, but they're part of the system, too. The ferocious consumerism in the US is easy to criticize, but it keeps the whole system alive, too. Alas, that's what most countries still want. They're scared of the afterwards. And I'm not an economist, so I can't have the most educated opinion on the matter. But I'm more inclined to going cold-turkey than slowly dying from addiction and taking the rest with me.
