Lots of bullshit jobs exist for a reason other than those jobs being useful. Politicians want to create bullshit jobs because it helps them get votes. And sometimes bullshit jobs exist to enrich corporate owners for government contracts - just look at almost any military contract where literally billions of dollars go unaccounted for. Or look at most construction jobs in the US that are regularly overbudget, late, and oftentimes not even up to the original requirements. And yet - those people still get paid and the people who created those contracts make lots of money. In fact, they usually make more money by being more incompetent, because they have to ask for more money to finish the job.

The question is always: who is benefiting from this?
