In just the past year, a UK accounting scandal forced out the Speaker of the House of Commons, for the first time since 1695. The Governor of Illinois was thrown out of office for influence peddling, and a Congressman was convicted of accepting bribes and storing the cash in his freezer.

Businesses haven’t done any better, from taking reckless risks with other people’s money, to Ponzi schemes, to insider trading.

Actions like these are leading people to demand more restrictions on business. People say banks should risk less, and pay their executives less. They want oil companies to drill less, and burn less. They want drug companies to charge less, but not do less R&D. Sometimes, this criticism is warranted. Sometimes, it’s not. But when people don’t trust you, they’ll find a way to force you to change.
