PITbull,
OK, now I think I understand what you're trying to say. I think.
Here's where I'm suspicious of the conspiracy theory (no, I won't call it ridiculous). What you're suggesting is that corporations' boards of directors are hiring CEOs with the goal of busting unions, even if it means shutting down the company.
I certainly agree that airline unions have gotten weaker over time. The first step along that path was airline deregulation. Before that, whatever the unions asked for, they got, simply by going to the CAB and getting fare increases to cover it. After deregulation, that sweet deal went away. But let's not mince words here...that sweet deal meant that these unionized employees were stealing from the public through legalized highway robbery, in the exact same fashion that the cable companies are gouging the public today.
Initially after deregulation was enacted, there were so many inefficiencies in the industry that it took a long time to start to reach the point of convergence. Slot control slowed down the convergence process, and enabled the airlines that managed to gain slot-supported monopolies in various markets to support the inefficiencies that had not been eliminated by the late 80s.
With the removal of slots, the protections afforded by the hubs went away. The inefficiencies gradually came under pressure, and the unions themselves came under similar pressure. In order to maintain their revenues (dues), they need to have as many people as possible covered by them. Thus, they're better off selling out the people they supposedly represent than risking having fewer of them to represent. AMFA has done an amazing job building a pyramid scheme for themselves by pretending that they're saving mechanics from their existing unions. In reality, they're taking the mechs out of the frying pan and into the fire.
Fact is, the unions haven't truly represented anyone but themselves since the 1950s in most industries. The airline industry was one of the last to make that conversion, simply due to the protections afforded the industry by government until 1978.
Sure, there have been quite a few moves by various government officials (on both sides of the aisle, mind you) to help along the demise of unions. But competitive forces have had a far greater impact than anything government has done.
