The global reach of Goldman Sachs Group, through a network of former officials, could help foster cooperation as U.S. officials reach out to foreign powers to calm financial markets. But it could also promote conflicts of interest.

Say “Bueller, Bueller” in a monotone and just about everybody in the free world knows you’re echoing Ben Stein as the drone of an economics teacher in the movie Ferris Bueller’s Day Off.

But while Ferris gave himself a day off, it would seem that Stein just can’t stop doing something.

Lawyer, actor, author, economist, television performer, talk show guest, presidential adviser, Stein, 63, belongs in the multi-tasking hall of fame.

The appointment of John Thain to head troubled Merrill Lynch proves, yet again, the long reach of Goldman Sachs.

Thain, currently CEO of the New York Stock Exchange, began his career as an investment banker at Goldman. He went on to become co-president and co-chief operating officer.

As the New York Times reports, Thain was chosen not only for his success at the exchange, but also for his background at Goldman.
