More to come, possibly:
Rule #1: I know we're all tired of the Left attacking corporations. Defend them where relevant. Don't where not. It's sometimes hard to remember, but corporations are -not- our friends. They aren't our enemies, but they aren't our friends, either; they're as likely to oppose capitalism as anybody else who would benefit from an entrenchment of the status quo. This is the #1 beginner's mistake.
Rule #2: We didn't get where we are overnight, we won't and shouldn't get out of it overnight. Remember that rule of law is critically important; rapid changes to the legal system are in fact -arbitrary-. They erode freedom, even where they purport to create it. Privatization of public institutions should be done through sunsetting existing systems, not destroying them outright.
Rule #3: Cutting taxes is fine, but cutting spending is better. Taxation is a long-term target, and "starving the beast" has not only been grossly unsuccessful, it's moved us deeply into dangerous territory. We have helped to create a coming state of emergency which may very easily be used, not to dismantle government power, but to grossly expand it.
Rule #4: Compromise when it gains you something, not when it causes you to lose a little bit less.
Rule #5: All regulation benefits large corporations. All. Consider carefully the difference between pro business and pro capitalism.
