It truly is impressive the lack of consciousness everyone has today especially on this site, those numbers were for individual traders who book investor and manager alpha for themselves, it's easier for people who are corrupted by the stupidity of comments like yours to relate to a family office (which they can look up for themselves).
Instead of the true fact that if they are individual traders they are then Sovereign entities, these create a 150-200% return on capital per year, meaning if you make 20% per year are are not just a failure, but are truly beyond useless, your mind, body and soul are working at 10% capacity, apparently to everyone this is the definition of success
The other interesting point is if you make 200% on $50,000 is that better than making 20% on $500,000, given the great ponzi scheme of life that everyone and the world lives by, the $500,000 is always the chosen path because that means $500,000 is in play for the world to induce failure on and survive which is how you have lived your unfortunate life, on both sides.
Whereas if you only have $50,000 in play out of $500,000 you get to live because there is only 10% capital in play which matches the 10% capacity you have, making every trade close to zero risk, which is even better if you go to bed early, wake up early, do everything you need for the day by lunchtime and are free to then do whatever you want, read a book, play some golf, sit in the sun, something you could only ever dream of.
