I believe that all progressive thought is founded on that one principle, "Do unto others as you would have them do unto you." That is the basis of equality, and that is the true basis of democracy. That is the basis for a single-payer health care system in which all of us carry the load of those who are weakest among us. What would you have others do if you suddenly needed health care and couldn't afford it?
We have to take on the opposition by addressing the core beliefs that they hold. People who stand for anything less than single-payer obviously do not believe that one's principles are worth the trouble, or else they simply do not believe in the Golden Rule, but rather in the survival of the fittest. If it isn't "convenient" to stand for single payer, then it isn't convenient either to do unto others as you would have one do unto you. That's playing one's advantage.
The basic sustenance of life and fundamental needs should be the responsibility of the strong, not the give or take whenever we please because it's ours kind of puke. The rich hold the goods and extend them in crumbs to the rest of us: knowledge, health, freedom from want, and personal sovereignty and dignity.
The most ignorant among us should be the most cared for. The most educated and resourceful should be the least.
