The middle class is the pot of money regardless of posturing and she was just baiting the traps with eco-class warfare yummies for the idiots in the middle class.
I don't exactly see Hillary's rich elitists firing their accountants and lawyers and filing the 1040 short forms any time soon.
Those words she floated were very caregully chosen and very deliberately spoken in order to obtain a result from a specific group, and it's not the rich or wealthy she was really speaking to. The rich and wealthy know that. Wink, wink.....Nudge, nudge........
Also, her husband said (almost) the same thing to a bunch of big donors in Texas, after he raised taxes in his first term. The news media reported it, and, ho hum, he got re-elected anyway.
So she is going with a game plan that has worked in the past.
