Barings Bank, and the Soviet Union, were demolished by one man, Leeson in the case of Barings, and Gorbachev in the case of the USSR.
Both men accomplished what they did accidently, so something similar could happen to the WT/JW Scam.
Perhaps a combination of the two mistakes made. Leeson was over-confident as to his investing (gambling) skills, Gorbachev thought his modernisation of the USSR was going to prolong its existence.
Perhaps a desire to go more mainstream coupled with fiscal ineptitude will finish 'em off ?
