It shifts to the sellers, not the buyers. That's because buyers are competing with each other which drives the expected return close to the general market rate.
Assume there's a magical oracle that tells you: this kid will generate $100M of wealth over their lifetime - to not get bogged down into discounted future value, lets say the risk free rate is 0% - but needs $500k for education and resources early. Without any investment the kid will become stuck in a local maximum in a shitty environment and generate $100k instead.
Market competition will bring the total sale amount close to 0.5%. Lets say it's 1%, although that's very high. Funds bought shares that are 'fairly' worth $1M for $500k, for a profit of $500k - not bad. The person gained $99M. Total distribution of wealth becomes more fair, not less.
