Very impressive. Nice to see it in pictures like this, of course everyone still ignores how bad the over all economy is and how much debt this economy is really in.
It's one way to do it - nothing really wrong with progressive rates like that, if voters want relative largesse from their gov't. The effect is to move dollars from income to assets (ie, "wealth"), which in and of itself is better for the economy than the excess consumption of trinkets that is promoted by the current approach.
