You have a good vision and your intention are what a lot of rich folks out there are lacking, else, there would have been some major turnaround in the strides of NGO's in their role in ameliorating social vices within our respective societies. I hope someday you make that so much money to carry out your dream for others that are languishing in all sorts of addiction problems, mostly gambling and hard drugs.
If you look at the NGOs, they are not so transparent because most of them can use the money to launder it and the money doesn't reach the people , in fact in my country there are floods , floods , and the people who helped with clothes, with food, the police are asking them on the way to pay for it, I think the solution to this is to take the bull by the horns and do it, because governments and entities often do not do it, greed wins them over.
