Plus, who would investigate? Sharad Powar is an extremely poweful politician (president of the Nationalist Congress Party and the secretary of Agriculture). No one is going to do any investigations. The players won't, the boards won't - they want to be in his position eventually, and the Indian public sure as hell won't. If you're in the system, you don't want to change it. You can hire family members as athletic trainers, take huge retainers, go on vacations on company dime, and you don't ever have to produce a thing in your life.
Do you really think the guy who went to the US on a 'fact finding' trip for four months on company money wants to change it? The guy above him is doing things that are much worse, and the guy below him wants to get ahead. It's a great setup. But with that setup comes the insatiable appetite for money, because no matter how much you make, someone will be waiting for their cut, and it'll never be enough.
The only people that are hurt are the young cricketers of India who have no facilities to practice in, no coaches to teach them, and no trainers to take care of them.
