Markets. Unless you don't believe in capitalism. Markets create competition. Competition creates incentives to lower costs. Its the lack of competition that's driving healthcare costs.
Better care. Its cheaper to diagnose and treat many diseases at early stages then it is to let people get sicker then try to save them when they show up at the emergency room.
People with decent insurance are more likely to get treatment.
If you get down to the fundamentals and really analyze them, there's no way that having healthier population is more expensive than having a sicker population.
Its like not understanding that poor roads don't save money versus good roads. The roads might be cheaper but the damage to vehicles, and losses due to congestion and slow speed, is greater than the savings due to bad roads.
That is one of the basic misunderstandings about government spending. A lot of the time there's no savings from cutting spending, there's just cost shifting and frequently more inefficiency.
Have you looked at the actual plans being offered.
Sample:
For $400-800 for a couple in their 50's they get between $1600(B)-$3000(S) in deductibles for care.
That is close to a weeks paycheck for insurance coverage that many can not afford. Even is the premiums are subsidized for the Bronze levels; the deductible costs do not go down until you increase the plan level. That delta may not be subsidized.
Government spending for
make work/publicity projects is not efficient.
Most times, those projects are heavily cost inflated.
How much government spending is needed becomes a matter of opinion and how one wants to see money distributed.
Take it out of the hands of the people and let the government distribute it according to their "all encompassing" wisdom or let the people decide what their money needs to be spent on.
If you think the government knows best on spending; then why even have a private sector; take and hand out goods on demand; a persons worth ends up worthless.
