Most people recognize that there are things which, when we pay for them collectively, benefit us individually. That's how we ended up with a regulated capitalist economy with some services handled by the commons. All proponents of health care reform want is for us to add health care to that commons, since for-profit health insurance is fundamentally flawed, and every other country with a standard of living meeting (or exceeding) ours has already realized this.

I'd hate to think that the sole litmus test for any scientific endeavor would become "is there any money in it".
