I worked in advertising for over a decade, so I can definitely agree with some jobs being a means to an end, but I disagree about the purpose of getting employees emotionally invested. In my experience people that are emotionally invested do better work than people that don't give a shit about anything more than a paycheck. They suggest improvements and argue with coworkers about how features should work because they understand the product and care that it succeeds.

> When did being in your products' target market become a precondition to being good at your job?

That may be a valid argument for many jobs, but I can't imagine who isn't part of PayPal's target demographic.
