She is smart. People who believe they're independent or in the middle (usually brainwashed lefties) always complain about one thing the most: There's too many loopholes for the "rich". Pointing out that crony capitalism IS the problem and not necessarily tax policy very well may satisfy their desire to put the screws to the rich. They maybe couldn't define it but crony capitalism and the corruption of it is really what they're concerned about.
I think you're absolutely right.
