By fair I mean free from bias, dishonesty, or injustice.
As far as what's been added to increase spending I was curious myself. I'm working from 2004 figures here however it appears that the amount of retired people and SSI recipients has increased about 45%, however our SS spending has increased 60%, so has medicare/medicaid. Does that mean we should cut them by 15%? I'm not sure. It's something to be aware of however.
What I'd like to see is more focus on using technology to reduce medical costs. All seniors should get a little device that measures basic vitals and allows them to video chat with their doctor so they can avoid the office visit. If I were a doctor this is what I would try to be doing. Kind of like doing house calls in a Ferrari.
Then we have defense. From 2004, Three years after 9/11, to 2012 we have increased our defense spending by about 47%. I think it's time to wind down or at least invest it in local assets instead of external operations. Go ahead and make the drones, SWORDs, MULEs, and exo-skelatons but keep them here. At least until we get the budget under control.
As far as increase in revenue since 2004 we're at about 30%. Spending 56%. Our Revenue to GDP percentage has gone down 1.1% and spending up 2.1%. A lot of numbers, I know but they are very useful. My source is http://www.usdebtclock.org
