What are the pros and cons of unions?

Also, what can be done to fix the cons of unions?


Can you provide examples of when unions helped/hurt a country/industry and why it happened?


Are there differences between public and private sector unions that affect their usefulness?

I find it better to think of it as organized labor in the same way that corporations are organized capital. Neither is inherently good or bad (though they should increase efficiency). When either side has too much power, it's bad for the economy as a whole. 

Corporations and unions, being run by people, will both tend to try to exploit the other for personal gain when they have the power to do so. 

As such, having one without the other tends to be a serious problem in the long run, unless there's government mechanisms to keep their power in check. And the government has a historically bad track record with that, due to these groups' ability to influence politics when they do become powerful.
