a simple question

Can anyone out there name a single industry in which a union presence hasn't ultimately proven detrimental?

I'm not talking about short-term benefits here, I'm talking actually strengthening the industry. Unions do bring about temporary, and artificially bloated, gains for their members, but in the end they end up strangling the life out of the company or industry. The rob their own future members (or would-be members, as the case may be) for the benefit of those of the present.

I can't think of any company or industry for which this has not already been the case or is not becoming the case as union benefits and demands become untenable. Can anyone else?
