They're not paying them for good looks
It was announced earlier this year that Bernanke had joined PIMCO as an advisor but this is a bit more formal.
Greenspan worked for PIMCO after leaving the Fed.
Whatever they're paying them, you can bet it will be worth it for PIMCO. It was earlier reported that Bernanke might be paid seven figures for the PIMCO job.
Trichet and Gordon Brown won't be working for free either.
Truly, no one is more qualified to buy bonds than the printmaster.
