As the right-wing Wisconsinite sees it, Democrats can have their new revenue if the revenue comes by way of policies Republicans like. Ryan sets an absurd goal — lowering spending to 20% of GDP — and ties this to smoke and mirrors. Note that first paragraph in particular: revenues must come from economic growth.Of course, this is the whole problem; the official Republican position for years has basically been that the only way to get more government revenues is to lower taxes. Of course there's no empirical support for the idea whatsoever.
And it's important to note that it makes compromise very, very, difficult. Whatever Republicans really believe, as long as their position is that the only way to get revenues is to cut taxes, when in fact that's not so, there's very little ground for agreement. I should note, by the way, that some liberals play the same game -- if you cut spending on such-and-such preventative measure, it will only cost the government more in the long run as whatever it is gets worse and produces long-run costs. I would say that there's at least more basis for truth in that story, but it doesn't lead liberals to demand no cuts in any program ever, or that every cut of every program is really a spending increase.
Anyway: nice catch!
