Yes. I'm sick of hearing it as well. I've put a couple people in their place about it in the last few weeks, and they had nothing else to say after I gave them the facts.
Richest 10% in the nation pays nearly 70% of the total taxes collected, us bottom 50% pays a whopping 5%. Its also a proven fact that as they gave tax breaks to the rich, the government had actually collected more. Less wealthy would go through the trouble of trying to hide their money from being taxed, and more of it would be. (Last parts just my guess)
