The point is there is no money to be made in Universal Health Care so they would not save anything. Plus, while Rick Wagner probably means what he says when he indicates that he is doing everything possible to keep GM out of bankruptcy (it'd look bad on his resume), Scott Sprinzen of the S&P sees exploding health care costs as the route to a bankruptcy led, union busting restructuring of the auto industry. Health care is now a weapon to wield against the working class the same way debt was used in the 80's to hobble unionism. I'm surprised LBO has not picked up on this. Your observations are correct, that is the ruling class is dead-set against Universal Health Care, but not out of simple me-too ruling class convenional thinking. There's a strategy behind it that reflects material interest, and it's working. At least for now.
I would point out the above strategy is frought with pitfalls, like an invigorated socialist/unionist movement that has finally decided enough is enough. The faultline is the Delphi bankruptcy which has yet to play itself out. Steve "I feel your pain, 'cause I'm causing it" Miller & Wilbur Ross have been successful rolling out the same game plan up to now, but this time, they don't have the element of surprise like they did before. Nobody was surprised when Miller declared bankruptcy in October and since then, workers are very much getting the sense that a lot more is at stake than just their own company. Workers are getting the sense that now is the time for a decisive showdown between labor and capital and if workers give-in, they will be surrendering 70 years of struggle and there will be nothing to protect them. Despite fabulous improvements in productivity in the last 25 years, there has been nothing but downsizing and outsourcing of jobs. Workers are increasingly realizing that concessions don't save jobs but only make the owners richer. The UAW's opening of the contract to make concessions to GM have shown that the ripple effect is real and broad based. Already, Ford and Chrysler are demanding similar cuts. Precedents matter and if workers can inflict enough pain on capital, this so called "new reality" can be shown to be a smoke and mirrors snake oil roadshow.
