Diapers, doing their job.
“Politicians and diapers must be changed often, and for the same reason.” — (Not) Mark Twain
Diapers accomplish exactly what they are designed for. We’ve designed a system, that makes politicians for who they are. We have none to blame but ourselves. No, human psychology does not change, but to add, we’ve removed all incentive to.
I know what you are thinking. This is a “blame the system, but not the perpetrator” argument. But ask yourself this, “What does being a politician really mean?”
