I don't like Facebook and M. Zuckerberg a lot, but in this case I fully agree. As productivity due to automation and digitalization will increase more and more, we simply have to accustom to the fact (and I actually appreciate it!) that not everyone has to (and can) work in every life phase. Thus there must be a solution to secure a minimum living standard for everybody.
I don't fear that the majority of people are satisfied with their basic income and stop working forever, because they want to earn more money than that to realize their aims in life ...
