My 'worst' job has nothing to do with what I perform as tasks during it; unless what I am doing is what I do best and choose to do and am entitled to do by virtue of superior capabilities, the job will still feel like rightless wage slavery, which is precisely what it will be.
However that would only make a job bad as I just described--my being the victim of injustice and lack of rights. The thing that would make it 'worse' is having to work for a pseudo-religious insane statist order-giving disconcepted freak who no matter how well I did my job, how much more than anyone else I did or how perfectly the results were achieved would neither respect me, nor appreciate me nor pay me decently nor allow me to teach
what I did, be promoted nor advance my career because of real capacity or greatness.
This sort of tsar-***-petty micro-controlling tyrant is "the drooling beast" Ayn Rand had her character Stephen Mallory describe in "The Fountainhead".
I have had such a mind as my boss, so I know that what she my teacher said about such collectivist brains was exactly true. But now there are so many of these now in so-called leadership positions in this failed nation, they have begun to threaten its very existence. At the imperial Washington level, regional levels, thee state, county and local levels, in corporations, academic tsardoms, media monopolies, bureaus--they're breeding like a plague.
Any job one can get working for such minds is 'the worst', if you're permitted by them to have a job at all; it's just a matter of degree after one has been stuck with such a job.
