ObamaCare does not benefit the majority, but no serious person expected that to happen.
ObamaCare does not save money for the majority, but no serious person could have expected to cover more people, with more mandatory coverages, with the young subsidizing their older and wealthier neighbors and that costs would go down.
ObamaCare does not even help those currently without insurance, although that is the one tiny corner of this massive power grab that some low-information voters might reasonably have believed. Instead of being denied medical care when needed (something that is currently illegal), these people will now be sent to their in-network provider, who will likely be so overloaded that the care will often be delayed until it is no longer needed. The poorest among us will get worse care, although they will have a little card with a policy number claiming they have insurance. At least they will have "free" birth control.
Who wins? Only those in power who want more power and those crony capitalists with the connections to profit off of all the money flowing through a monstrosity that used to be the world's greatest medical system.
