Those are excellent questions.

The root problem of course, is as long as there are for-profit health insurance companies...then healthy people will also have to be part of the covered.

Everyone likes (or should) the preexisting condition exclusion and a lot of conservatives even like keeping their children on their policies.

The obvious issue is that if preexisting conditions cannot be used to determine rates, then you have to have a pool of covered people who are not likely to use their insurance.

There is no other way it can work...in a for-profit model.

It really boils down to whether you have a fundamental and humane belief that a government taking care of their citizens health, is more important than fighting wars, having a military that equals the next 7 combined, giving corporations a handout by allowing them to underpay their workers and therefore allowing the workers to qualify for benefits...and supporting the military-industrial complex.

Most of the civilized world long ago decided, that taking care of their citizens...is the most important function a country's government can do.

That we have people basically screaming that if one person is getting health benefits that they don't think should, then 'scrap it all'...says pretty much all you need to know about the self-centered right.

As for what the Repub's come up to replace the ACA, I foresee a push by the Trump extremists/cultists to push for a lack of a replacement that basically says...'tough $hit for you.'
