Sovereign Wealth Funds are an excellent tool for meaningful change in the world today and help contrast the differences between peoples at large as represented by those protesting the CPP investment in Private prisons and their counterpart, that being the investment funds set up by Wall Street.
That segment of the population investing in those Wall street funds (84 percent of all stocks are owned by 10 percent of Americans) cares about nothing but a higher return on investment.
The people at large (call them the Commoners) do still have a conscience and care about things other then how much in it for them as individuals. Indeed this can be applied to collective wealth held in Common as compared to Private property as well. A parcel of land held in common will always have those voices of conscience worried about how it will be used. There no such opposing voices when it Private property.
