My primary concern here is you and Agema understanding the situation. I'm not pleading for it to be repealed, I'm reasonably certain that would have minimal impact at this point.What concern are we left with? You're saying this system is so awful because some parents are choosing to insure their kids, and you think this is bad because the kids might not care about it? And this is the ACA's fault for... giving the parents the option?
Like, to speak well of it, I like the rule change for pre-existing conditions. Health insurance rejecting sick people is just a con. But requiring insurances to cover them would raise premiums for everyone, that's just the only way the math works profitably. And raising prices with no other change would drive people out who would rather save their money, exactly the people you don't seem to think exist. Which is why the mandates were made, to make sure there were people contributing more than they received to support those who cost more than they pay.
I appreciate the intent of the law, though would prefer a system not based in insurance rather than codify the insurance based status quo. I would like for you to also understand the ACA for what it is.
