No, just stop flying private jets. Try to do online meetings and if you really need to be somewhere use commercial aircraft for travel to lower your footprint. It's easy. This hypothetical businessman can lower his footprint to level of South American villager with some effort and planning. As for the children of wealthy people I would rather have a millionaire with 10 kids which can receive proper health care and education (and with a bit of luck share their wealth with less fortunate people) than 10 kids living in poverty.
