That's true for some jobs, but I'd be very surprised if anyone enjoys cleaning shit, for example
For what it's worth, I don't mind a bit of higher dimensional data reduction when processing raw multi channel data, or geophysical world modelling (magnetic fields, gravity, radiometrics, etc).
I'm pro "everyone cleans their own shit" but the meaning of a garbage truck driver could immense compared to a honest hedge fund manager or a VC Patagonia vest.
Cleaning time of our own shit hopefully won't be a full time job. We'll just figure out the ones creating too much shit and educate them as a society :D
