Indexes should not be blind

The importance of Indexes (and their well-paid providers) has expanded dramatically during the past few decades. First it was the institutions which benchmarked more and more products, now it is the avalanche of passive money, not only through ETF's, that hugs indexes slavishly.
But given the fact that the world has become more complicated it can no longer be right to leave value judgements out of index construction. There simply WAS no investment in Venzuela, China etc and not too many people cared about the environment, social issues or human rights a few decades ago.
