Your wrath is misdirected. The stranglehold on power comes from the Federal Bureaucracy and the liberal establishment not boomers.
Politicians pander to people who vote, not to people who don't. People who vote in large blocs tend to get what they want, right or wrong. The federal bureaucracy and liberal establish do not have power in and of themselves, they have the power bestowed by voters who think it's someone else's responsibility to take care of them.
