As for the indebtedness, I was speaking about the key layers of the economy - personal/household debt[1], corporate debt and public (government) debt[2].
We've grown accustomed to the debt as a regular part of our life, of how our households, businesses and whole countries work. This is very dangerous.
Regarding the unaccountability of the for-profit players, mind you, I'm pro-free-market as anyone here. But this piece of news[3] makes you rethink what happens at the highest level of the market, how the largest enterprises become uncontrollable institutions on their own.
