The US system has lots of problems, but reducing them by even 1 improves the situation. It may take fixing many to make the situation “good” by some standard, but not to merely improve it.
I think that's likely true. But interestingly it doesn't, theoretically, have to be. In principle the combination of a multiple factors, each of which would move us significantly away from the global maximum (therefore constituting "problems"), might put us at a local maximum where removing any small number of them might leave us worse off.
You're absolutely right. Even the Affordable Care Act, for all its faults, is saving real lives. It is a very real improvement over the situation before, but it's not the end point yet. More steps need to be taken. All at once or one at a time, whichever works.
