Perpetual Motion, Big Foot, and Administrative Cost Savings.  They're all myths.  But that won't stop Jim Doyle from trying to convince you otherwise:

Every child in Wisconsin would be eligible for low-cost health insurance under a proposal billed as the most sweeping reform of the Medicaid system since its inception in 1967.
...
The plan would enable families to buy health insurance for their children through the state for $10 to $60 a month per child, depending on family income.
...
Doyle's plan would be financed from administrative cost savings by simplifying and merging Medicaid, BadgerCare and Healthy Start - three existing state-and-federal health programs - into a single program called BadgerCare Plus, the Department of Health and Family Services said.

In the entire history of the world, when has any government program, ever... ever... resulted in less waste and bureaucracy?  I'd honestly love to know the answer.  But let's assume that somehow, through the magic and wonder of "government efficiency", these cost savings are realized.  Do you honestly think that it will be enough to subsidize insurance for every child in the state?  Granted, not every family would opt in their child... but I imagine that the number of children covered compared to the current program will increase significantly, and not even "administrative cost savings" will be enough.  I wonder if Jim even has done any studies to figure out how many children might enroll of it were offered.

So how are you really going to pay for it Jim?
