Instruct: Classify the given comments as either toxic or not toxic
Query: How do you figure? Vermont didn't implement their single payer plan because what they were planning didn't pencil out. A significant part of why it didn't pencil out was that there were significant exemptions in terms of who had to pay in.

It seems to me that Vermont's experience says that their plan was flawed, but is not  a comment on the concept of single payer at all.
