I don't see what the hoopla is all about !
First of all, Oprah donates to other charities as well. She just doesn't brag about it. She and her celebrity friends stepped in to help the people in New Orleans after Katrina by donating money and building homes while the government, including FEMA twiddled their thumbs and were wrapped up in red tape.
While this donation seems like a pittance,
I'm sure that with the 31 charities she supports, she's donated well over a billion over the years, including $400 million to Morehouse College and funding 400 additional scholarships there. She has donated to other education institutions and started a school for African girls as well.
Oprah: Charity Work & Causes
I have a great deal of respect for Oprah and love me some Dwayne Johnson. Perhaps asking for donations from others speaks to the fact that many people
do want to feel they are doing something to help. That has been proven by the number of donations that come from us regular folks after other disasters. At least they are not donating to people who are already super rich...like Warren Buffett donating millions to Bill Gates' foundation. WTH?!
