Big countries are not ready to work on anything because they are taking their own profit which is enough for them ICC is just like White-Elephant which is having deep pockets and enjoying their power for having good amount into their pockets if they are sincere about cricket then surely we can have good changes and entertainment for fans.
Well, the big countries have to think about how to keep the smaller nations grow with them. If they do not take them along they would be left very behind and then this White-Elephant with deep pockets couldn't generate money because people won't be interested to see one-sided matches.
If countries like West Indies, Bangladesh etc could play better we would see more audience seeing the Big three playing with them also you will get more sponsors and ads. When you know it will be a one sided series, who will be dump to put money on sponsorships and marketing? I do not understand why ICC does not develop this business oriented sense
