Wut? If you're loaded, retired etc, work can be used to keep active and social, for those of us who are neither, we go to work for the £££'s.
There's a difference between going to work for the £££s and the £££s being the only important thing about the job. You spend a huge amount of your life working, if that time is making you stressed and unhappy then it is not worth getting a few extra £s for. For most people a bit less money for a lot more quality of life is a worthwhile trade.
