Given that technological advancement exists to improve the longevity and ease of life, does it really make sense to suggest everybody should work as much as we do for a living?

I understand that some jobs are important and necessary but a lot of jobs are replaceable through machinery and programming. We actively try to make living easier through technology while knowing there will be a decrease in the jobs necessary to support our lifestyles. Any thoughts on how to create a sustainable livelihood that promotes both technological growth and a prosperous life?
