Tell that to the departments that are getting $1.1T less over an 8 year period.
Between the sequestration and the lack of budget increases, the US has been going through a period of federal austerity.
Of course, expecting fiscal responsibility from a government is a fool's errand. Screaming like a stuck pig and running around yelling "AUSTERITY! AUSTERITY!" if one even breathes a threat to feed them less, and then blaming everything bad that ever happens again on the AUSTERITY is exactly what I'd expect from them. What on Earth will they actually do when something bad happens?

We always had a surplus at the end of the year and the boss would tell us to spend it on anything and everything because if we didn't, there would be less money in funding the next year.
The amount of waste was incredible and it made me angry. It's why I went into the private sector/started my own company.
You also almost could never get fired. We had so many bad employees that basically sat to get a paycheck and take up space. If you are really lazy, it's great.
Because of this game that is played, it's very difficult to tell if a department 'ran out of money' or just spent it to meet next year's budget.
There's tons of waste in any large organization. In my experience, private companies have more waste (resources and personnel) then public organizations as they have much less oversight.
Although since that seems to be what a lot of EU governments are calling "austerity", perhaps we have had it.
