There is an element of truth to what you say, but I also think you're being dismissive. It _doesn't_ exist today. For one simple example: how many times have you heard people talk about payraises etc., "bumping me into a higher tax bracket so I actually lose money"? I've probably explained it dozens of times to people I consider entirely intelligent - many of them believe there's this little window at the border of each taxation tier that makes no sense to be in.
