"Health Care" Problem? Or Insurance Problem?

Why do we continue to call the issue a "health care" problem when it is really an insurance, or ability to pay, problem? If we spent as much in additional taxes or medicare payments as we do in "health insurance" premiums, we could cover all Americans, regardless of income, with the finest health care in the world, while denying nobody. So what is wrong with that? A few fat cat insurance executives would be out of jobs (oh, pity poor them - - NOT!!) and investors might have to find other opportunities - such as renewable energy stocks, for example. Not such a bad idea? Providing health insurance coverage for all is not the same as "socialized medicine", and we have to make that argument loud and clear to rebut the assertions of the other side!!
