Former U.S. Treasury Secretary Lawrence Summers isn't happy with the Republican tax plan, and it's not just because he has a different set of ideas as a Democrat. More fundamentally, he says Republicans are making false claims: “When you have -- and I hate to be in a position of using this word about our government -- when you have senior economic officials making claims that are made-up ... it’s very hard to have a dialogue, and compromise, and get to a good place.”

Summers is also worried about the effects of a tax cut for the rich during a time of considerable social turmoil: “There’s a lot of unhappiness and anger out there … It’s really hard to see why focusing a corporate tax cut on those at the very high-end is going to do much to assuage that anger.”
