two different things.
Your incorrect statement is the current limit on out of pocket maximums. My plan already has a max out of pocket of $18,000, just looked on Cigna's website and verified.
It would appear their are some "cost sharing" possibilities for Medicaid/Medicaid equivalent enrollees in terms of a possible deductible... maybe that is something you are concerned about, but they actually cap those cost sharing limits to 5% of family income. So, I don't believe that is unreasonable.
Again, I am not saying I am a fan of the plan, but at a minimum do some research before you start talking about republicans killing people over the stinking plan that I would venture a large percentage of republicans don't even feel like it goes far enough. The current state of any of the plans being thrown out there will do nothing to impact healthcare costs in this country.
