A necessary though not so welcomed reminder

Sir Martin Wolf’s “The dangers of living in a zero-sum world economy” December 19 is a splendid, necessary but of course quite unwelcome aide-memoir for all of us that feel that we have been somewhat unworthily blessed with peace and prosperity during our life time and worry that we will not be able to guarantee the same for our children.

I fully agree that we will have to count on human ingenuity to save our descendants from the dark ages that already lurk close (hugo chávez), but to that end we also need to keep on believing that goodness and badness does not add to a zero-sum human condition
