Not surprised in the slightest. I guess we're emotional animals. Assuming the same compensation was delivered in their paycheck.

I'll just save that money myself, maybe invest it MYSELF, then take more than 2 weeks off because my investment grew.

I guess it helps "force" people to take time off. I know many people that wouldn't take time off until they were forced by management, or their PTO was going to expire. Therefor losing money.
