American Health Care Act

Here's a good explanation via USA Today: "What does the Republican Obamacare repeal bill actually do?"  Among the provisions:

The American Health Care Act would let insurers charge older customers five times as much. That’s intended to draw more younger — and healthier — people into the individual insurance market.

If I remember correctly, the original ratio of older health care recipients versus younger Americans was over 6-1.  In other words (unsurprisingly), older Americans use six-times more health care.  Obamacare perverted the very definition of insurance (risk pools, actuary tables) by setting this to a 3-1 ratio.  The kids realized they were getting a bad deal and stayed away, preferring to pay the tax penalty instead of expensive insurance.  Because of the looming death spiral, the Obama Administration had to launch the pathetic "pajama boy" ad campaign to trick the kids into joining the insurance pool.  But they didn't and insurance companies started to lose billions and here we are today.
