Work life balance is a priority for most people but the issue is that everyone is only concerned with their own work life balance, rather than society as a whole. These people work themselves to death and trample on others in order to reward themselves with work life balance later on in life. Then you realize that if only everybody helped each other out and stopped trying to compete with each other, we wouldn't be in this situation. Unfortunately this is how life works and is a classic case of Prisoner's Dilemma [1].
