Elected officials are able to get rid of these so called "experts" though.. they aren't permanent structures in our government.
But when you become entrenched in politics, it's very, very difficult to get rid of you... and it becomes your seat until you die.
Public service shouldn't be a career where you just continue to gain power and money to the point you are too big to fail. You become beholden to too many entities and they in turn ensure your re-election every cycle.
We put term limits on the Presidency, on most governors, on most state house and senate.. on most elected posts with the obvious exception of the federal House and Senate. The only reason they aren't in place there is because the corrupt politicians won't vote against their own well being.
I'm even ok with grandfathering in all the pieces of shit in Congress right now.
We need to get term limits imposed if we are going to ever hope to drain the swamp.
