Bellemere, One of the things you listed is a problem, I think:
the requirement that everyone have insurance. Rather than fine people, I think (leaving children out, because I think parents MUST have their children insured) that the penalty/limited enrollment that is used in Medicare would be more appropriate. There are people who don't sign up for Part B because they are healthy and don't want to pay the premium. Later, when they decide that "hey, I'm sick, I need insurance" they are (unless very low income) limited to enrolling to January-March of every year, with coverage starting July l, and they pay a penalty for late enrollment. Similar rules apply to Part D. And for Medicare supplements - if you miss the initial enrollment period, then a person is subject to waiting periods. I think that type of regulation would be more acceptable to people that the concept of a fine.
As for much of the other, I believe that as long as insurance companies are primary in our health care system, there will be unnecessary costs and there will be uninsured and underinsured people. It's one thing to deny someone insurance who remained total uncovered until they got sick. It's another to deny someone who has remained covered through employment and COBRA and is looking for individual coverage but has a medical condition--that's unfair.
A tax on "Cadillac" plans seems reasonable to me - for years we had employer-paid coverage on which we paid no income taxes, while others who had to pay for their own insurance because their employer did not provide it had to pay their premiums out of after-tax dollars, and could only deduct a percentage of the premiums off their income tax. So basically what we had was $14,000 in extra, non-taxed income.
I think the cuts to Medicare Advantage Plans are reasonable. It's unfair for others in Medicare to pay higher premiums so that these plans can get a subsidy. Other reductions in Medicare, if they prove too damaging, will be corrected rapidly - the Medicare population is growing every year and their voice will be heard. I also believe we all need to do our part to stop fraud and abuse.
But, who knows.
