The tragedy of the commons

Liberalism is about doing the same thing over and over and expecting a different result:

GREEN BAY - For the second year in a row, a bicycle sharing program in downtown Green Bay is seeing some problems. The bikes, meant for public use, are disappearing.

The city began its green bike program two weeks ago. 25 bikes were put on the streets and almost all of them are gone. The same thing happened last year. [emph. added]

(Hat tip: Berry Laker.)  Paris has similar problems with its program.
