In other words, 62% of your revenue goes back to the taxpayers that provided that revenue. If anything, I'd be complaining about the other 48% if I were you.
>Implementing Obamacare
The argument that Medicare costs x and support y people, and Obamacare costs 2x and supports 2y people, therefore full universal care would cost 100x and support 100y people is flawed.
Clearly, if the US went universal, the massive administration costs associated with HMOs and such would no longer be an expense to be paid. Instead of being a large employer within your currently broken system, you replace the system.
There is a reason your health spending is almost double per capita to the next highest nation, and it has nothing to do with your population.
