you might have to shift your perspective a bit. if you work in a bigger structure(e.g. government) a managers job might be to keep as many people working as possible. also, his measurement of success is by how many people he manages, not how much he delivers. ever heard people say "i manage a team of 100 people"? i've heard people say that, and i can assure you not a single person (that mattered) asked, but how efficient are they in return.

so if you start optimizing so that a single person can do the job of 5 people in less time you not only threaten their job security, you also question the manager, and you become trouble for accounting. therefore you become a liability.

you could argue that, wait a minute, by freeing up their time, and yours we can make more money and more other things, and in theory you would be right, but in practice that's not how it works. there's a certain budget, and you as an individual won't make more that that budget.

also for the institution it's better to keep that budget split up for those 5 people. that way they can charge 5 people on that budget, and accounting won't have to cheat. if you don't, then suddenly you'll have to find other jobs for those other 4 people otherwise they're kinda cashflow negative on their salary.

Above a certain size, the goals of the organization, and the goals of individuals, diverge sharply.
