We could add the EPA Energy Department, Department of Education, etc etc etc. We could also use as example of poorly managed Social Security, Medicare, Medicaid, Fannie Freddie just about any of their programs. The reasons as simple

1. Government doesn't need to make a profit they have your tax money

2. Congress votes on issues based on securing votes ,bribes, boondoggles, favors

3. Congress has a short attention span and once they implement a program it is forgotten unless or until their is a crisis, a crisis by the way created by their incompetence.

There is so much abuse and fraud in many programs but it won't be stopped because of the political process.

Take the food stamp program. Republican want the fraud stopped but the liberals spin it as those greedy white guys want to take food out of the mouths of the starving.

Folks we can't have it both ways. You choose
