I would call a living enough to live on, pay bills , have some spare for entertainment, this is different in different countries and even different ppl have different ideas on what are essentials and what are luxuries, people with children usually need more income than single people etc etc.....
if a person is making enough to not need other employment/sources of income they are making a living no matter what country they live in.
I wish the Americans could see there is a whole world outside of their borders - I live in a vain hope that this worldwide Bitcoin thing will open some eyes
