"It has long been established,however,that the payment of taxes is generally not enough to establish standing to challenge an action taken by the Federal Government. In light of the size of the federal budget,it is a complete fiction to argue that an unconstitutional federal expenditure causes an individual federal taxpayer any measurable economic harm. And if every federal taxpayer could sue to challenge any Government expenditure, the federal courts would cease to function as courts of law and would be cast in the role of general complaint bureaus."
But then who can sue? If Congress sets aside $50 billion for the church of the FSM who can sue to stop that? I'd like to think that any American who put in at least one dull, red, penny could have standing....
Rammstein, taxpayer suits long ago removed any standing from people seeking to sue because their tax money is being used in ways with which they disagree. The first lawsuit was over, I think, AFDC (welfare), and the Supreme Court said "no standing."
So, essentially there is no legal way to even challenge new welfare programs that violate the constitution.
It is left to the ballot box.
Which is why we are getting more and more and more of this stuff.
