Fannie Mae-No Politics (FNMA)

"History and experience show us lifetime is simply too long and too isolated So maybe 15-20 year terms

Yes, life tenure is too long. In other countries people are appointed to such positions in their mid fifties or later and they serve maximum of another 5 to 10 year term before they retire.
