I hated my life when I worked at this style of company.
When I worked at (a beverage company), one of the unfortunate realities was that the company did not really compete to make their money. The profit at the entity I worked at was completely based on the price of ingredients that was set by a parent company. We could have reduced complexity and improved efficiency by large margins easily, but it didn't matter because the parent company would have clawed back a larger share and pumped their profits, while our efforts were of no benefit.
In this aimless zombie corporate mode, they hired people without much thought, and everyone was busy looking busy (8 hour meetings were common for "developers"). However, if you are doing something for real, people don't see any point in helping you out; so even if you really do want to improve things (in my case, I wanted to help the poor souls on 2ch who had to work on the weekend because of poor internal communication that prevented hand-offs), no one wanted to lend a hand.
Since profit is not a big deal, and everyone simulates being busy, no winds up in charge, and the inmates run the asylum. If you are the guy in the unimportant job, you suddenly realize it is a bullshit job and are constantly in fear of your job vanishing. Moreover, since you cannot accomplish anything, it is nearly impossible to find a new job when the company inevitably encounters reality.
