i have no qualms with MrBeast's business model. using his youtube videos to raise money to help people in whichever way is certainly not a problem. most of the entertainment industry is doing a lot worse (by keeping the profits to themselves).
the question is not, who is doing more, but whether what anyone of us is doing has any lasting effects. so it matters how the money is used. most of what i have seen from MrBeast is giving random amounts of money to individuals, which sometimes can be helpful, but often only provides short term relief. his recent examples of paying for eye surgery or funding an orphanage are an improvement over that, and if that is where MrBeast's philanthropy is heading, then i am all for it.
Keep on working on fixing our system, but it doesn’t make sense to complain that others aren’t when you are extremely unlikely to succeed.
