I think it's easier to hide this from kids & teenagers than coworkers, family, and adult friends though. They're generally sheltered from the money aspect of society - they have no reason to be digging around in the financial news looking for their dad's name. But adults read enough of that news (particularly if you stay involved in tech & business) that someone will eventually come across it, and "so and so's actually a millionaire" is a pretty fruitful gossip topic.
