This study (and they are quite transparent about it) doesn't focus on the number one cost, housing. There is some room for technological innovation there but it's mostly a policy issue. The best-paying jobs in the US are highly concentrated in a few areas, and at the same time cost of housing is skyrocketing in those areas. We could do a lot to improve people's wellbeing by figuring out how to make housing much more affordable. (Technology can help with transit, building techniques, and better remote collaboration software; but policy is required for zoning/planning, and for transit as well).
