The bigger concern, IMO, is insurance is tied to employment. The time you get your massive bill is when you get very sick after being fired/laid off and your COBRA is up.
The next biggest concern is the ACA which is the greatest scam ever pulled on Americans. It started out as, what would've been, universal healthcare. Instead, it simply played into the insurance company profit centers by forcing people (now by law) to hold some kind of insurance or pay a large tax fine. So you're stuck paying $1,500 for sub-par care on a bronze plan with a massive deductible and no limit. So much for "increasing the competitiveness of the market".
Healthcare spends more money on lobbying than any other sector in America. The solution isn't to start breaking it down with crap like the ACA. That will get gutted by the bought and paid for politicians (which it did). What we need to do is begin by repealing citizen's united, limiting campaign contributions to 0 from industry professionals (in both their professional and personal capacity), and fire the congressmen taking the most money from them.
They don't have hearts. They have large wallets. Hit them where it hurts.
