Unfortunately, having your own office is costly plus it doesn't satisfy the boss's need to see a large group of people actively doing his/her bidding.
1) revenue 2) results
Those who got distracted by other crap tended not to be as successful by objective metrics. Just my experience though
Most want to build their political cartel, protect it and build it for their own good.
I've even seen bosses who purposefully punish high performers out of fear that they might become a threat to their job.
I am looking at new office space now and I am thinking about setting up glass cubicles and having an office sound system that will pump out white noise.
I am concerned about aesthetics though.
