Making Charlie Sheen Seem Rational

The Difference

 Unions in the private sector are a way of organizing private interests, those of employees, against other private interests, those of a company's owners, for economic gain and for protection against unfairness.
 In government, workers are already protected against unfairness by civil service laws.

 Economically, government unions pit a private interest, that of employees, against the public's interest, that of taxpayers and voters.

And that is why I am a Trade Unionist and not a public sector union supporter.
