We're now reaching a stage where people can live comfortable lives. Back in the past there was always the problem of dying early, but that's decreasing now and I expect there isn't much difference between the average, and the very rich in terms of how long they live, at least in the UK. I lead a pretty average life and it's quite comfortable - I don't have to work terribly hard to earn a living and I can also expect not to drop dead in the near future. I think many people would be satisfied with an average home and job, but with more free time to do other activities, or to spend more time with their children.
