> I don't understand -- whence this idea that Sweden has big problems?
It doesn't, of course. But Sweden did go through a nasty stretch in the early 1990s, due primarily to a proto-Thatcherite deregulation/bubble boom/bust of the real estate market. They had to nationalize the banking system and devalue the kronor.
Over time, investment rates do matter, because exchange-value is something produced by real live factories, not the business plans of e-punters and the electricity scams of oil pipeline profiteers.
