This is true. Humans have always strived to make their own lives easier. It is just that the rewards of an easier life are not being distributed to the actual people doing the work. Instead, a disproportionate amount of the gains have been going to the investor class.

My experience makes me think that people very much do _not_ want to be obsolete, and that being obsolete is devastating to one's sense of identity and social acceptance. I do think they also have the drive to work less, but there are plenty of people who do things for fun that other people would call "work".
