On the flipside, though, money correlates to power, and having fame and wealth exponentially increases your ability to enact the change for which you campaign. Also, *most* liberals understand full well that as long as the exemptions are there, you would be foolish not to take advantage of them. Hell, I've had that conversation with many, many liberals, even those most opposed to the rich paying substantially smaller fractions of their income in taxes, and virtually all have agreed that not taking advantage of available tax breaks is idiotic. If nothing else, you can then turn around, take that money you saved on your taxes, and spend it on pushing for tax reform. (As opposed to paying millions of dollars you don't need to pay to a government whose spending priorities you almost certainly oppose.)
That said, I will freely admit that people who are, say, campaigning to get pollution cut while driving a Hummer and gallivanting around the world on their private jets irk me just a wee bit.
