I can see this going a couple different ways, but by far the most interesting scenario I feel is the one where countries that don't pass the smell test start floating to the top.
If all of the sudden, countries that have been driving their economies off the road, like the Venezuelas of the world, float higher in the rankings, can we put more nails in the World Bank's coffin? They give advice with disastrous consequences for impoverished countries.
I think it was Reagan advisor Jude Wanniski who used to refer to it as the Destroyer of Worlds Bank.
