O'Keefe was chosen as NASA administrator precisely for the purpose of cutting costs.

As long as there are no accidents, it could seem clever to cut costs, also those related to the Shuttle's safety.
But there was another accident.
It's fine to criticize NASA for its bureaucracy or for its huge spendings. But is it the right thing to do?
What's the cost of safety?
Now, if we get back to the Apollo era decision making, is it the pre-Apollo 1 era, the pre-Apollo 13 era or the pre Skylab 1 era? (Skylab lost its meteorite shield and one of its solar panels, at launch).
Besides, launching 2 Saturn V rockets per year is different from 5 or 6 STS's.
