I don’t think it is intentional. I think it is more like a phenomenon. I think entire companies can potentially be bullshit. It’s not like the people working there aren’t making the company money so nobody is deciding to hire people for no reason. It’s just that these people and businesses are mostly working bullshit jobs. So much of the economy is based on doing nearly pointless work so it enables further pointless work.

Really it depends on your exact definition of pointless. If our only goal is to survive then we can probably succeed at that with 5-10% of the work that is being done now. Everyone else isn’t doing something that is directly contributing to humanities survival. That seems a little extreme as I personally believe that things like entertainment, art and making life more comfortable are all meaningful to society. There could be some definition of pointless that a majority agrees on that implies that 25-50% of jobs are not doing much of anything.
