May not be in our lifetime, but this is definately where the world is heading.
A world where even without working you will be able to have a normal good life lacking of poverty. And then those that do work will have a life that is relatively better than yours, but everyone is still ok.
That will inevitably be the future we're heading for. But it's also very scary considering human nature. Imagine if only 50% of the population works. There we will have working people with superiority complex that will treat the non working people like garbage despite already having a better life. Then there will be the non working people who despite not working will feel entitled to the same things. And they have the great excuse of there not being enough work for everyone to strengthen their view. Then there is of course the possibility of having not enough workers because most people rather not work and still have a decent living. It's all really scary from a human perspective.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
