Because alleviating suffering is not the goal. Reputation laundering, giving friends and family cushy sinecures, optimizing tax liability, and placating the masses and governments are the goals.
Maybe I'm overly nostalgic, but the reputation laundering in years past didn't seem to preclude significant financial gifts to things the general public benefited from, such as scholarships, public parks and libraries. Bill Gates for his part has done a lot to prevent the spread of infectious disease for the most vulnerable around the world.
Something definitely seems to have changed since those days. Warren Buffett is one of the top 5 most influential men on earth and does nothing besides spout folksy platitudes about how "it's not right" that his secretary pays a bigger percentage of her income on tax than he does. Even Jeff Bezos' divorce was a blessing in some ways as his ex-wife committed billions to charities that Bezos himself would not. The less said about Musk taunting the United Nations Food Programme's ask for $6bn, the better.
