So I think there are many layers and levels to sport engagement, and also there are clear studies that wealthier societies pump more into sport. Studies do show that more well off societies get more super athletes etc. However there is also other data: https://eu.usatoday.com/story/sports/olympics/2020/02/24/sur... Yes their parents do need to be well off enough to support them, but these are people that still struggle and I certainly think there is a lot of data of poor people trying to get out of poverty via sport, and those will also be the most vulnerable to be pushed into destroying their bodies for it too. TLDR I don’t think you will find many tech CEO sons doping to be the next Armstrong.
