Hell yes. Building something valuable enough to reach the top 3 means you've created massive utility for millions of people. That's an achievement worth owning, not apologizing for.
Ashamed. No one becomes top-3 rich without a system that lets one person hoard absurd power while millions struggle.
I would be totally proud. Hitting that level of wealth means you built something that completely revolutionized the world and delivered massive value.
Hell yeah I'd be proud. Turning ideas into that much value is the ultimate flex.
