I think I agree with the point you are trying to make, but I would do a hard distinction between entrepreneurship and allocating funds on the stock market.
Strong arguments for what I think you are trying to say by Sometimes, other people are more intelligent / skilled / harder working are made by Peter Thiel in his "Zero to One". The argument he makes is that there are more people who have succeed more than once. (success defined here as a multi billion business)
It is certainly possible to beat index funds, many do so, some of them are mostly lucky, some of them are mostly skillful. - That is the trick ain't it? The hole point is that there is no way to distinguish between the two (a priori) and no way to deduct if it will lead to future success (posteriori).
