It really boils down on how many people need how much resources and how many people produce these resources. You can argue over who should be your bourgeoisie, should it be the political elite or the entrepreneurs or should it be inherited or or should it be the the people from special blood or religion or should no one be bourgeoisie and everyone should be working but you can't really argue over the resources and work done that is need to sustain a society.
You simply cannot have all the population on planet Earth retire on their savings because you cannot eat the numbers on the screen. With automation, robotics and other technologies we can increase the productivity and as a result we can afford to have greater percentage of people in leisure but we are nowhere near total machine labor. In fact, the percentage of non-working people probably is not that different than the past because despite the increase in productivity we also have increased lifespan which results in large number of retirees who consume the resources for much longer than before.
In dominant countries you might have the percentage higher and live off on imports from countries where everyone works much harder but the gap evaporates as these countries catch up.
So, the trick is to be part of a society that is so much advanced than the rest that their produce can buy off the produce of the society that relies on hard work. You can have a lot of bananas from Honduras if your society can make great apps that Hondurans love and willing to trade their bananas but this scheme falls apart when Hondurans start making their own apps and now you need to grow your own bananas.
