What would have to happen for a great health insurance policy in USA to cost like $80 a month for an adult?

no matter what age and only $30 per child? By great coverage I mean like a plan that covers 85% of anything medical that the insured needs up until they spend a max of $1,000 annually at which time it becomes 100%. Such coverage would be an improvement for the great majority of americans. So how can we accomplish something that gives that great coverage and is as cheap in terms of premiums paid by enrollees?

What would it take to have the cost that low? The care equivalent to what it was like in the middle ages. Or you have to pay 3 times the amount you pay now in taxes if you want the same quality of care you get now.. Insurance cost so much mostly because the cost of the actual care is very expensive. Get the cost of the care down, the cost of the insurance would follow.
