You are correct, at some point the capacity to do their job would be compromised by continued cuts. This is the first significant cut they have had to deal with however.
I used that to help illustrate the point.
But it can apply to the first 10% cut as well, depending how much 'waste' there is.
And I have no reason to assume there is 10% waste in the Secret Service, or even much of any waste that will be found to cut if the budget is cut.
Hence the cuts will affect something that matters more.
The agency told the President they'd be furloughing a lot of agents as the alternative.
The President said he was not in favor of 'cutting the income of agents by furloughing them'.
I think that's a sensible position. But some people - not saying you - just will always simplistically, ignorantly, blindly say 'ya, cut 10%, good bout time they get a cut of waste'.
So what I'm saying is, on the one hand, there's a bit of 'real issue' to waste. There absolutely is real and excessive 'waste' in any organization that there should be processes to find and reduce. But that also the issue is largely a myth and political device used for demagoguing and excusing cuts to good programs and should not have that sort of ignorant and blind support always in favor of cuts saying 'the govenment is filled with waste'. The sequestration is absolutely not about 'cutting waste'.
It's good to understand that there are some things a politician can get great public support for by demagoguing. And it's hard to think of one easier than demagoguing against 'waste'. Because he can ramble on in a speech about waste and the audience will cheer and love him, he'll demagogue it, real or not, for that reason. It's a bit like Joe McCarthy and communists in the government.
The people don't realize they're being demagogued, and anyone who tries to point out the guy is demagoguing is attacked as 'being in favor of waste' BOO!!!!!
Republicans need themes to get elected on, and 'waste' is about the best they have.
Now, they haven't been entirely responsible when in power about 'waste', and so their ability to milk the issue has lessened a bit lately, but in the past it's been a golden goose.
While I'd say there was some merit to that Al Gore commission I mentioned, I don't think Clinton didn't understand the politics that he'd get credit and take the issue from Republicans.
Thing is, a politician can want to screw you badly with his policies and not talk about them - so he can demagogue on 'waste' and get elected. So they do.
Whenever you hear a politician talk about waste, it's a red flag for BS. That's how the issue is actually used.
Defense is a bad example, because there actually is so much 'waste'. The actual programs include all kinds of waste. I'm not referring to programs for the troops, but weapons and contractors.
In addition to the waste we have today, every war has had big examples of profiteering - disgusting cases of people ripping off the government. I've read the history where in the civil war companies would sell horrible boots that hurt the troops for high prices and similar things to make a buck. Truman's claim to fame in the Senate was the Senate commission on huge WWII profiteering.
But let's say there's a case where a president does want to cut defense that's not legitimate waste and it'll be politically unpopular - a likely way for him to do it is to claim 'waste' as the justification.
