I have a good friend whom I've known for years who is a Teamster. To be honest, I feel your ridiculous and long winded account of Teamsters is quite off the mark.
Perhaps if you saw and heard things from the other side you might change your opinion. But I doubt it. It appears you already know everything their is to know about what it's like to be a Teamster, and what they put up with. Thanks for that shower of wisdom.
Again, my knowledge about their job isn't first person, just coming from what my very good friend has told me for the last twenty years or so. I can tell you this though, your 1970's era opinions of unions being all powerful are about as anachronistic as holding up your lighter during Freebird at a Lynyrd Skynyrd concert.
My friend has described in detail how they continue to "get fucked" everytime their new contracts come up. And yes, he tells me the details of thier contracts, what has changed, how it used to be, etc; He actually doesn't like telling me most of it, but I'm quite interested in how that process works, how they negotiate, etc;
The Teamsters don't get their cake and eat it to, as those with a Mussoliniesque political bent would have everyone believe.
Unioins, and especially the Teamsters are a pale shadow of their former selves.
Now to the real point.
Yes, we will have driverless vehicles in the not too distant future.
Yes, most if not all of the driving professions will disappear quite rapidly after that happens.
Yes, that will put even more people out of work, with no or little hope of a future profession now that their livelihood has disappeared.
