No imagine.
The government takes over the healthcare system, and in several years or a few decades, that system is losing money as fast as the post office, medicare, and social security. How will the government address the issue? Will they keep raising taxes, or will they begin closing down hospitals and clinics, and begin reducing services? The goverment has lied about and failed to produce with every other major program they control. How can you believe anything they tell you about this proposed idea?
Do you really want to put something as serious as medicine into the hands of the idiots in Congress? These morons pass massive spending bills without even reading what's inside them for crying out loud.
