Do you know anything about the medical industry?
I don't work in the medical industry and have never claimed to be an expert. I do know a thing or two about economics. Namely, if a consumer can't pay for a product, that consumer won't consume that product. You are falling in to the supply-side trap by assuming that if a product is made or offered, it will be consumed, always. That's simply not true.
If all her husband's clients with Medicare lost their Medicare tomorrow, it is dishonest to say that every single spot would be filled with a client with commercial insurance. It wouldn't happen.
Face it. She's preaching against something her family benefits from. It's pretty obvious.
