Answer 1

I believe the answer is:  Government bailouts for failing corporations.

Adam Smith was a prominent supporter of letting the Free market decides who would survive and who wouldn't.
He believed that government intervention (such as bailing out failing corporations) would disrupt the balance in the market and would risk market crash.
