In his San Francisco Chronicle column "Rich Man Talking," Harley Sorensen lies about Steve Forbes' flat tax proposal, writing, "His flat tax proposal amounted to a kind of Robin Hood in reverse concept: Lower the taxes for the rich and increase them for the poor."
In fact, under Forbes' proposal, the poor would pay no tax at all. More information on the proposal can be found here.
The rest of Sorensen's column ("They want a return to slavery," etc.) is so ridiculous it doesn't merit a response.
