Going to the moon or Mars won't fix any of our earthly problems, it will just give us another place to screw up. Why don't billionaires try to fix hunger, homelessness, or similar issues? There's no money in it for them or their stockholders.
Both Gates and both Bezos are doing just that.
"The Bill & Melinda Gates Foundation is the second-largest charitable organization in the world by assets, with an endowment worth nearly $70 billion. Through the foundation, Gates has reportedly donated
more than $50 billion since 1994 to eradicate diseases, promote education, and advance gender equality."
"Last year, Bezos gave away $122.2 million and has pledged around
$12.8 billion in charitable donations, according to The Chronicle of Philanthropy. His mother, Jacklyn Bezos, and her husband Miguel, gifted $710 million to the Seattle-based Fred Hutchinson Cancer Center in 2022."
"The couple, who have four children together, had their
divorce finalized in July 2019. The $38 billion settlement kicked off MacKenzie Scott's journey into charitable giving.
Just two months before her divorce, Scott had signed the
Giving Pledge initiative, committing to giving away half her wealth.
In 2022 alone,
Scott donated almost $2 billion to 343 organizations.
She topped that in 2023, with almost
$2.2 billion worth of grants donated to 360 organizations."
And I bet Donald did not donate a penny to anyone. He has rallies every week when he bags for money and millions of dollars are donated to him.
