You don't think labor unions exploit their membership to enrich those in control of them, thus giving them a reason to survive even when there's no actual labor abuses to be solved? The enrichment of labor bosses is old news, and their frequent manufacture of problems to then "solve" is also not a shocker. Unions should be event-driven, not continuously polling. The fact that they're the latter at all is because the people controlling them saw selfish opportunities.
I'm a badge-carrying socialist, but abusive labor union hierarchies are just as sickening as abusive corporate hierarchies. They're one and the same, both controlled by sociopathic scum risen to the top of the pond.
