"The power structures" want people to need to work so they have to work for them. Better to keep you occupied with the rat race than have you spending time advocating for political reform.

Which is why work expands to fill all available time. They want you to have a job, because what they don't want is what you might do if your time was your own. For some subset of "they" that represents the most malicious pricks.

The thing that happens if they win is that everybody still has a job even if they're not doing anything useful. Which in a lot of ways is what's happening already.
