The Ryan plan calls for cutting the top marginal rate to 25 percent - lower than it has been at any time in the past 80 years. That in itself should tell you that this is a deeply unserious proposal: anyone who tells you that we have to face hard truths, that everyone must sacrifice, and by the way, rich people will pay lower taxes than they have at any time since the 1930s, is just engaged in a power grab.
From Ryan and Taxes
The Ryan plan should not be viewed as a budget. It should be looked at as a statement of ideological principals. If it were really serious about the budget, it would trim the military budget and corporate subsidies.
