I think wealth is more equal to total free time left on the planet. So total time minus time spent working to provide things for survival minus time spent surviving (like cooking, sleeping, running from lions). The washing machine is invented, lots of peoples' wealth skyrockets. Food gets cheaper, people's wealth goes up.
Looking at income is a short-sighted definition of wealth.
