http://www.bbc.co.uk/news/magazine-20243493Jose Mujica, president of Uruguay says:
"I'm called 'the poorest president', but I don't feel poor. Poor people are those who only work to try to keep an expensive lifestyle, and always want more and more. This is a matter of freedom. If you don't have many possessions then you don't need to work all your life like a slave to sustain them, and therefore you have more time for yourself"
Seems like an interesting and wise guy to me.
