In my very backwards and barbaric country every person, regardless of their profession, receives a state paid pension and we have a notion of social safety net. There are homeless here, like everywhere else in the world, but elderly citizens can retire knowing they will be taken care of.
On the particular case of judges, and on this I have the luck to have been explained how things work, upon reaching 65, a judge is retired and recognized by their service, with a very generous pension, as the career is considered as being of high strain.
No one should be forced nor allowed to work until their dying breath and this is a prime example for it.
