I won't defend those who run the "big 3" automakers. Unless something "changes" (I think twice whenever I use the word these days) I don't know why auto-making should have any better chances of success in this country as have other forms of manufacturing. I think there is a lot of blame to go around. Inequities in pay for US workers vs everywhere else is a big factor, maybe even the biggest.
My main reason for buying US cars was always the thought (no longer applicable I suspect) that parts were easier to find for the US cars. If my Chevy broke down in the middle of nowhere chances are any local gas station could fix it. When I had an Audi (long time ago) that would not have been the case and I probably would have to have been towed to the nearest Audi dealership (few and far between in some areas) for an always expensive repair.
Anyway, if you google something like "government intervenes to settle gm uaw strike" you will note that in many cases the car companies hands are tied, particularly after having to shut down for two months due to a strike (and note the current news paints planned one month cost savings shutdowns as a disaster all by themselves).
So when the UAW leaders decide it's been long enough since they flexed their muscles to make new demands, they are almost guaranteed to get some comprised version of what they ask for, even if it takes the Feds coming in to force the issue (the threat of federal action usually has the desired effect).
OK, so a strike happens, and is settled, and the UAW gets half of what they asked for. Then what?
Well, first of all they have typically just struck GM, not all three, because GM was the biggest. This is a great system for Ford and Chrysler of course.
BUT, after the GM strike, Ford and Chrysler make similar deals with the UAW without a strike. Government willingness to step in and establish a "going rate" for UAW workers (in both dollars and benefits) pretty much makes the Chrysler and Ford negotiations with the UAW "done deals".
The End?
No. If you work at any company with both union and non-union workers, the non-union workers can almost be guaranteed to get all the benefits that result from a strike of unionized workers, possibly with some adjustments for the advantages of not being in a union (paying union dues, not being forced to strike to support some other workers grievance, etc.). So whatever deal is made with the UAW is soon replicated all over the industry. While there are non-union plants in the US, I don't buy that their level of compensation ends up drastically lower than the level for the union shops.
So. While I'm sure the heads of the big three are nincompoops in many respects, stupidly giving in to the unions isn't one of them. That decision is pretty much forced on them. What happens with the unions, can pretty much be laid at the feet of the unions, both members and leadership, and the press who continually portray union members as victims even when they are over compensated, and to government officials that end up caving into to public pressure genned up by the press. (Not to mention "special interest" campaign funding from union lobbyists.)
At the same time when near slave labor is available in parts of the world, the car companies stand out in offering higher compensation to domestic workers in both good times and bad. This has been a disaster in the making for years.
Bottom line is, if we want to be part of a world economy, with access to all the cheap services and labor that is out there, then things have to change here domestically. The benefit of being part of the world economy for the majority of Americans will be (has been) cheaper goods and services, particularly of certain kinds (clothes, electronics, and other "Wallmart stuff"). The downside will have to be concessions that some people here have to make in their compensation.
The alternative is that we take a knee-jerk reaction of going back to isolationism (economically). Maybe it would do us good for some of us to go back to making our own clothes and building "Heathkits" because we can't afford the alternatives.
In the same way that last weeks top Rap artists are compared with The Beatles, I'm quite sure the press will end up calling these days a depression, even if mathematically they don't measure up. But maybe the advantage of having a few years of hard times, regardless of what they are called will be having another generation of "depression era survivors" that can remind everyone else of the value of savings, and conservation at the family level.
I used to make fun of my aunt and uncle who would tear napkins in half before passing them around to guests. These days I do a bit of my own napkin tearing. It no longer seems so silly at all.
