Noble prize winner Paul Krugman in "Destructive creativity" :
"I don’t always agree with Naomi Klein, and I don’t always disagree with David Frum, but Klein wins this one hands down: Frum worries that financial regulation might crush “the creativity of the system,” Klein counters that “we could all do with them being a little less creative.”
This is usually framed, less colorfully, in terms of “financial innovation”, but the point needs to be repeated again and again: at this point, there is no reason to take it on faith that cleverness in the financial industry is a net social good. Unless you can provide some clear evidence of productive innovations since regulation began to unravel — and ATMs don’t count — the balance of the evidence suggests that smart people have been devising ingenious ways to concentrate risk and direct capital to the wrong uses."
