It isn't the original question, but I thought it was a legitimate one.

The cardiologists and their like can be outvoted. That's how it goes in a democracy. But the number of people who lose on net may be greater than the number of people who win on net. So the only way it gets implemented may be through... let's say "undemocratic" means.

Note well: I'm not advocating this. I'm just pointing out that this may be the way the politics works out.

Sure, I can imagine the points grb423 may have been implying, but by presenting them as a series of vague rhetorical questions it makes it hard to respond directly.
