"We have rather fewer people who lack liquid assets in that way, but obviously most individuals can't have enough wealth to shift the larger market.  If the knowledge they have is of a form where they can't convince others, all they can do is place their own bets and wait to become wealthier and accumulate more of a track record.  If the knowledge is shareable, there are all kinds of arrangements which naturally allow the individual to capture some fraction of that knowledge's value to Civilization.  The classic literary trope involves making a deal with a mad investor, but for ordinary shareable knowledge you'd just make an ordinary deal with a more staid trading firm."
