How could Madoff not have made any trades for 13 years?

No problem for a sociopath.  Consequences, cause and effect are far beyond the developmental stage of most sociopaths. Joe Jett of Kidder Peabody never thought the parade would end either.

Look at that “little boy lost” look.

Robert Kegan in “The Child Behind the Mask: Sociopathy as Developmental Delay.” In W. H. Reid, J.W. Bonner III, D. Dorr, and J.I. Walker (Eds.) Unmasking the Psychopath. (New York: W.W. Norton), 1986. (1986), p.  68:

The sociopath can sit still, inhibit immediate aims, defer gratification.  Indeed, if he did not have these abilities (which most latency-age children also have), people would not confuse him with an adult even with his adult-looking body (which most latency-age children do not have, and which has more to do with why latency-age children are not confused with adults than people realize).  [Kegan is saying I believe that it is the sociopath’s adult looking body that gets him into the door of adult life which he is actually unsuited for and absolutely untrustworthy in.]

In Jackass World sociopaths are given free rein. “The government is the problem, not the solution” — Ronald Reagan, airhead bubblehead and in my opinion a likely pseudologic sociopath (title of memoirs: “Where’s the Rest of Me”).
