George Soros is mentioned a lot by detractors of Progressive politics, his book The Alchemy of Finance is really good, deep theory on market behavior when anticipation of trends factors in and alters the course of trending markets. Such things can make people a lot of money if they anticipate the psychological effects of market forces and compensating behavioral adjustments by large numbers of people affecting the markets. This can also be done with social capital, by adjusting one's communication to influence perception of trends in order to make trends better. Or worse,if one is black-hat trolling. Works both ways, depending on who's doing it.
