Sure, but there's competition there. If you can figure out how to achieve the same results with fewer layers of management, or have your management act more efficiently, you'll reap the rewards. So any bullshit managerial position is inherently unstable: as soon as one company figures out they can do without it, it'll vanish from the industry.
> The second thing is that if your plan worked (companies get rid of all bullshit jobs), then society would collapse. .001% of the people would end up with 99.999% of the wealth, everyone else in abject poverty. The more technology evolved, the more extreme this inequality would become.
We're at pretty close to full employment, which suggests there's plenty of genuine work to be done. Remember that eliminating bullshit jobs wouldn't lower productivity (by definition), so redirecting that effort into productive work would massively boost overall productivity and be good for everyone. Even if we were to run out of productive work (which seems a long way off), surely we can find better things for idle people to do than sitting around and obstructing the productive people.
