How does it do that any more than simply buying a stock would?
Buying a stock,I have the advantage of picking (A) company “I” think will do well.What we’re doing now,with 401K and IRAs is taking money and throwing it across the board,investing in many companies.Most don’t even know the companies they are invested in.That might “prop” up a bad company with money gathered from individuals and invested in it,if it is included in a particular “fund” account.
