Romney and Obama all understand the idea of a large risk pool to help everyone one. The Mandate is necessary. Once this whole thing morphs into Medicare for all, we still all will pay, but it will more than likley be via tax deductions from our paychecks.
Permitting a large portion of the population to bilk the system, having the rest of us pick up their tab (in the form of highter fees and medical costs) because they assume they will never get sick or injured, does hurt everyone and they will no longer get that free ride. Many with financial difficulties will be exempt and I will gladly pay into the pool to help those that are unfortunate. Many others will be covered under mom and dad, or on their own...and it's time they put on their big boy undies/big girl panties and act like responsible members of society, instead of assuming they will get away with not paying their bills by simply visiting an emergency room.
