Great, let's have single payer then
Actually single payer would be a cheaper alternative than Obamacare - for the government, individuals, and companies. However it will lead to some of the typical ailments of single payer systems - long waits, falling medical salaries/profits, reduced pharma research, etc.
As I have mentioned previously, if universal healthcare is view by society to be beneficial to implement then single payer is the preferred, most-cost effective alternative. There are plenty of countries (Germany, U.K., Canada, etc.) which can be used as good models for implementation. Many have both a public option and then private insurance which individuals can opt for instead (with slightly increased premiums). The U.S. should consider walking in a single payer direction. Imagine the increased profits at companies when they do not have to pay large amounts of cash to cover employee health benefits under the current private system.
