Terminology discussion: The phrase bubble economy accurately describes the inflated, vulnerable aspect of corporation valuation, stock prices, housing values, etc. But it sounds too cute and gentle. Yes, lots of people lost their homes, businesses, and jobs, but it was all just one of those things that hippies and yoga teachers sigh and can regard with "radical detachment." There's a Hindi word for this, I've heard it but can't recall it. Yet you see my image, I'm sure. Yes, a bubble burst, but bubbles do, sometimes. Though bubbles are pretty things and who would discourage them?
We need something uglier. What we call "bubbles" are pimple economies, boil economies, cyst economies. They need to be lanced, then supervised to makes sure nothing unsafe lands on the innocent. It takes time and attention. Libertarians talk a good game about limited government, but they need to jump on opportunities for government to supervise the lancing of boils as well as can be managed, recognising that everyone in those scenarios is likely a crook who needs the lash, not "market freedom." Once you've crossed a certain line, market freedom is for Other People, not you anymore. I'm sorta big on David Stockman at this point, who I wish could be put in charge of something important in the economy.
I think terminology matters in the PR battles of culture.
