The leadership of these mega-unions has not been concerned with the welfare of the line employee that is actually hired by the companies that deal with unions. Those little people are cash cows for the legalized racketeers that set up the extortion to begin with. Unions as they have existed since about the time of the New Deal have been a combination of some kind of vague Karl Marx theories, and bully-boy criminal elements. But the industrial and trade unions are a dying breed, with the unrelenting export of the blue-collar jobs to foreign shores, or the growing entrepreneurship of small businesses that rely on a very small cadre of workers loyal (mostly) to the employer, usually single ownership or family owned. And unions do not prevail in every state, which is reflected by the flight of these same business operations away from industrial states to more pastoral lands far from the home of giant conglomerates, or even offshore. In these days of UPS and FedEx, the suppliers need not be adjacent to their industrial customers, just able to deliver on short notice.
Unions have become dinosaurs, no longer able to adapt to the realities of modern industrial outsourcing. Not necessarily that they cannot, they will not. When this generation of union members is gone, the unions will die with them.
I hope your right, but I really doubt it.
As long as there is funding for unions they will exist and support liberal policies and candidates.
