We need to think WAY beyond what we know.
As a very tiny, tiny part of looking ahead, this AM, NPR interviewed a restaurant owner discussing the matter of "Tips" (to insure promptness), and what it would mean to the food business, and eventually, to the business of food production as an industry. Food production... not restaurants' future. A matter of "for want of a nail...."
As much as we have experts in every field of endeavor, I believe we're still at the point of trying to save the "shoe". Not likely in my lifetime... maybe 10 years, but very soon, Artificial Intelligence may provide answers that mortals are not genetically constituted to comprehend.
My textile worker dad, back in the late 1940's, told me...
"Bobby... the machines are doing so many of the things that millworkers do today. When you're old enough to go to work, you'll only have to work 30 hours a week."
Take from that, what you will.
Personally, I believe that we (the world) has the tools to be perfect, safe, and ultimately rewarding for every individual. The only lingering restrictions are the bad seeds of greed and ego.

My plan:
Early, intense education and nurturing of the very young... birth to age six.
Assessment of intelligence and leadership ability at age 15. From there, to build a totalitarian world/state.
Within the next 30 years, I think this could be possible.
