A solution starts with... No one owns the health of young-healthy people but young healthy people alone, or else you are a collectivist. They should enjoy their fortune for their own benefit, but they should be mandated (as in the tax interpretation of the mandate) to save their insurance cost in case of an emergency through a health care savings account, and with 401k free money type of contributions.
Universities should not force students to buy insurance through their university-own or university-provided health care. College students are relatively young and healthy, and universities exploit this to their advantage, not the student's advantage. At the end of a four year degree, students are coming out with student-loan debt and without having saved for their health care during their healthier years. Universities do not own, and should not benefit, from the health of the young and healthy.
Regulate employers health related contributions so that it is used for the profit of the insured, not the employer. Some employers use health care as part of the compensation package which allows them to game the system to their benefit, not the employee. Comapnies like Google and Facebook employ individuals who average 30 years old, and google has recently been accused of discriminating against older individuals. Is this because health care costs is part of the equation in who they prefer to hire? People with well funded health savings accounts would help revers age discrimination.
People with average health, should pool in risk pools of their choice--foreign or local. Individuals and families should be able to use your savings to schedule procedures with a different health care provider, or in another state or country where cost is significantly lower.
The safety net was meant for old, extremely sick and poor people and they should be helped by the government. No arguments about this. We have to help those in need, but define a clear metric to draw a line so that the system is not abused and remains sustainable.
Think of this people's health plan as a normal distribution. With relatively few healthy (self-insured) and extremely-sick (government-insured) people in both extremes of the distribution, and with the majority of people in the bulk of the bell shape figure buying insurance of their choice that range from health savings accounts to 'Cadillac' coverage.
Make people in government more responsible for their health care cost.
Force the full disclosure of the health care bills to people, and pass malpractice reform so that people sue for any abuses. Force hospitals to list the cost of standard procedures, and if a procedure is not standard and has additional cost, disclose the reasons for that. No one will fight an unfair bill like some one who is paying for it from his/her own funds, and this will help keep costs in check. Malpractice law suits should be a right to any patient, but it should be reigned in just enough to limit abuse and to benefit patients, not lawyers, or unfairly punish doctors.
Prohibit companies from sending 'unpaid' bills to people that have already been paid by insurance companies. The bills--or invoices of the cost an list of procedures--should have a large red notice across that tells the bill has already been paid or not.
For those who exceed a reasonable minimum in their health savings account, allow for part of their health savings to be used towards the purchase of a house, to increase the equity of their house by reducing the principal, home improvement, or lower the mortgage of a property they already own.
Allow health saving account funds to be invested in safe bonds and equities. No speculation should be allowed with this money.
This idea should be rolled out gradually, and it should start with forcing the young to save for their own health only so that no one else benefits from their health. When the young-and-healthy grow old and they have saved enough for their own care, or pass it to their children who would then have a head start in their health saving accounts, then we will have an increasingly improving generational people's health care system that is sustainable and reduces costs.
