I'm not really in the business of defending billionaires but I think at least one of them, the guy who brought his son, was involved with charities:
"He works with his family's Dawood Foundation, as well as the SETI Institute - a California-based research organisation which searches for extra-terrestrial life.
"Shahzada is also a supporter of two charities founded by King Charles - the British Asian Trust and the Prince's Trust International."
He sounds (sounded) like a good person.. I do find it interesting that the other billionaires don't have any mentions of charitable works in articles I've read in them.
