Let's just never mind that anybody currently insured and being treated for anything will instantly become someone with a "pre-existing condition" the moment Trump, etc, cause that person's individual insurance to get canceled. Then that person in the private individual market won't be able to purchase insurance that will cover their newly labeled "pre-existing condition", even if they don't go a day without insurance. That's the way it worked before in the individual market.
 Here's another news flash, medical inflation is about 5% per year. The current private insurance "age tax" adds another 3% to 4% a year on an overall average, as the subscriber gets older, which the lucky ones do.
 As you cut subsidies for people in the pool, more currently healthy people of all ages drop out. That makes the pool worse, so rates go up even more for those that already don't get a subsidy. The only people that truly don't "need" insurance are those that are very, very wealthy.
