Thanks for leaving a comment. I believe that while there are some people who use donations for purely self-interested purposes, there are also those who donate chiefly for charitable reasons.
For example, Andrew Carnegie paid for the construction of Carnegie Hall, John D. Rockefeller donated $80 million to found the University of Chicago, and Mark Zuckerberg donated $100 million to the Newark public school system. Even if they reap some benefits from their donations, the rest of society also benefits greatly.
It's kinda like the Clinton Foundation. Money were funnel to their own bank account instead of helping those who really need it. I'm not doubting Mark contribution, but I do have my doubts.
Understood! You have your doubts for good reason.
