It's just not worth the effort to look at little cuts. A few hundred million here and there just isn't worth our time. The big stuff, well, we can't cut that because it's the big stuff. You cut the big stuff and the economy goes in the crapper more. We should be able to trust the military to do the right thing with their $700 billion each year, without us asking a bunch of questions. They're pros! They need to be strong, so we can threaten foreign dictators with Tomahawk strikes, or roll over foreign countries run by bad guys when it's needed. If not us, then who? We also gotta build new carriers and jets, because our old ones, while still the envy of every other country on the planet, just aren't up to date.
As for entitlements, we owe it to our citizens to keep them well fed, sheltered and medicated, whatever the cost! It's how we've become the most prosperous country in the history of the planet. Plus, it keeps children from having to take their aging parents in when they're broke or sick. We all know that's a hassle. Good health comes from good insurance and that makes it possible for us to live much, much longer. And that's obviously a good thing. Everybody wants to outlive their organs and their brain. Who doesn't look forward to the day when you're cast aside by your family and placed in a home, living in a pool/pile of your own waste, burning through the remnants of your savings while playing bingo? Plus, you might qualify for one of those scooters. Nice!
So, I really don't see the need to change anything. It all seems to be going pretty well.
