You can call me names all you want. I'm a grown man, it doesn't bother me. I don't see how calling me a racist (?) disproves anything I wrote.

Leveraging the purchasing power of a large entity (such as the federal government) and cutting out inefficiencies (such as insurance companies) can have an effect on costs. However, even if the BEST outlook on this is assumed, this would be no more than 20% of the total cost of providing health care. And it would very possibly be much less.

The mathematics, as Iowa City pointed them out, are simple. Adding ~50 million people to the pool, adding guaranteed coverage for pre-existing conditions, and then subtracting 20% from the total cost (again, best possible estimate for those who believe in publicly-provided health care), still leaves a huge overall cost increase. Probably close to half a trillion dollars per year. The non-partisan CBO found as much.

Do you have any numbers to counter-act this estimate? How much will "preventive care" save? Yeah, I know ... "a lot." But how much?

Please tell me you have something more to buttress your arguments than accusations of racism.
