The problem with the cost of healthcare is not insurance, it's the COST OF HEALTHCARE... When an MRI costs $2800 and only takes 20 minutes, that's thievery. When open heart surgery costs upward of $250,000 ... that's greed.
Instead of spending the trillions that the government is spending arguing and plotting about insurance, here's a good solution:
Build a super hospital in each state. Have that state's citizens register by proving they are a US citizen (birth cert.)... Then when someone gets sick, they call for an appointment and go get healed free of charge...
