Read Heading off a Cliff? by law prof Michael Gratz and then decide. It's concise and really worth reading. Here's the abstract:
The major tax policy challenge of the 21st century is the need to address the nation’s fiscal condition fairly and in a manner conducive to economic growth. But since California adopted Proposition 13 nearly forty years ago, antipathy to taxes has served as the glue that has held the Republican coalition together. Even though our taxes as a percentage of our economy are low by OECD standards and low by our own historical experience, anti-tax attitudes have become even more important for Republicans politically, since they now find it hard to agree on almost anything else. So revenue-positive, or even revenue-neutral, forms of tax reform—at least as long as the GOP maintains its legislative majority—are politically impossible. The sad truth, of course, is that the coming tax cuts cannot possibly be the great and simplifying tax reform that the President and Sixers claim and that our nation so badly needs.
