Where is this sophistry written in LAW that appropriations are for, "Programs that benefit all Americans equally" along with its precedent to override settled LAW in US v. Butler or the Constitution?
Your second (maybe it's your third, hard to tell in that illiterate sentence) guess is correct: It's in the Constitution. The part already named.
Example 1: An appropriation for a bridge repairs on I90 between the Idaho border and Missoula, MT certainly does not effect the citizens of Hawaii, but could well benefit those in the region using I90 in that area and those outside the area for the commerce it carries, all in varying degrees, but CERTAINLY NOT EQUALLY! So are you saying that bridge repair appropriation was unconstitutional, and if so cite the Article, Section and Clause in the Constitution or the SCOTUS decision that would support such a claim of unconstitutionality!
You assert, "The Fed govt has no authority to do things to benefit limited groups...."
Example 2: Really? So you are saying that a limited group like all of my fellow WWII, Korea, Vietnam, Kosovo, Afghanistan and Iraq vets should not be entitled to VA benefits because the VA doesn't benefit those who DID NOT put their ass on the line during those conflicts. Where the Hell did you come up with this logic???? So Veterans are a "Special Interest Group" to you? That is irrational in the extreme. So are you claiming that VA appropriations are unconstitutional, and if so cite the Article, Section and Clause in the Constitution or the SCOTUS decision that would support such a claim of unconstitutionality!
Don't even try to characterize me as obtuse.
I don't have to. you're doing a fine job all by yourself.
(patiently)
The Constitution authorizes certain powers. Among them are the power to regulate interstate commerce (covers your I-90 bridge) and the power to run national defense (covers the veterans and their medical needs).
All clear so far?
And for the things it doesn't explicitly mention, there is the so-called "Welfare clause". Which limits expenditures for things not mentioned, to only programs that benefit all Americans (referred to as "General Welfare" in 1789).
For programs that benefit smaller groups ("Special interests") (this means the ones NOT specifically covered in the Const already), the states or the people must do those if they want it done. The Fed govt is prohibited from those.
Now that I've pointed these things out to you, you can no longer pretend anybody thought the "Welfare clause" must cover anything and everything the Fed govt does, even I.C. and Veterans. One section of your obtuseness has been exposed and removed.
No charge.
