Extract from today's Economist magazine:-
"It may not feel like it in the West, but this is, in many ways, the best of times. Hundreds of millions are climbing out of poverty. The internet gives ordinary people access to information that even the most privileged scholar could not have dreamed of a few years ago. Medical advances are conquering diseases and extending lifespans. For most of human history, only a privileged few have reasonably been able to hope that the future would be better than the present. Today the masses everywhere can. That is surely reason to be optimistic."
