You will not find a single health care system where older people are not receiving a disproportionate amount of health care.
Well, of course. That's not the problem though. The problem is being mandated to buy into the healthcare system or get fined, and of course the possibility that the health care system won't be there when you or I are at the age to need that level of health care. It's mandated to force the younger people to sign up and support those who will be using most of the medical bills, much like Social Security, but at least with Social Security, you are supposed to see a return on your forced investment (and if we did, it's a good thing), but with this.. well, you're not getting your money's worth until you're either injured or up there in age.. If prices/coverage on Obamacare were better for people who need the bare minimum, this wouldn't be such an issue.
But this happened simply because Obamacare got twisted by the insurance lobby, such as them going back on the promise of "if you like your plan, you can keep it". This was supposed to hurt private insurance by combating some of their shittier tactics, and yet insurance stocks went up during the roll-out? It's obvious something went wrong here.
