My problem with unions is not theoretical but practical. Theoretically unions are fine. Having worked closely with several unions, while never being a member, I have found the unions that I have been exposed to to be bureaucratic, corrupt, and rarely acting in the long term best interest of their members.
Over all unions in the US have simply failed in the market place. Unions do not appear to to be meeting the needs of workers. Union membership has been declining for decades. The recent fragmenting of the AFL-CIO seems to be an acknowledgement of this failure.
