Bug or feature?
It's not the we can't enjoy ourselves, it's that the exhaustion of work affects the kind of enjoyment we seek. Instead of going for a nice, long empty walk for free, we feel we have to spend $30 at the movies. Or we don't have enough time to cook, so we spend $50 on a restaurant. Both of these activities keep the "economy" flowing, by constantly moving money out of our hands.
I don't believe us working hard enough to ensure that we can only entertain ourselves by spending money is a diabolical plan. But I think the evil part is when we're influenced to think that we need to spend all that money on ourselves...
Exhaustion might be a very real effect, but I don't think it is usually a goal of an employer.
