Why is it important that civil rights movements be "fueled" by those affected most?

the conditions that made the byzantine empire vulnerable to attacks by the muslin turks were the sack of constantinople by western crusaders, the conquests of the sultanate of rum, presence of rival kingdoms and finally the set up of fiefdoms at the empire which were owned by the ghazis (turkish warriors).

basically means the stoc market is going down since   dow is one of the most sucessful buiness it would be a tragedy for it to go down and it ensures the ruinty of the stock market
