Because we're talking about part of the government.
One of the biggest things I disagree with republican on is that "government should be run like a business" no... it should not
So "running government like a business" is a way to ensure tax money is being spent effectively and efficiently
to be clear I dont think that is the best way to accomplish that goal, thus why I disagree with it, but it is not "profit" that drives that statement
It came about because far far far far far too often government programs and spending are judged by their intentions, not their actual results.
No it is not. That is reality today. Almost no government programs or spending is measured on their results.
I would love for you to prove me wrong, and show me a government program where the resolution for any failure of that program was not "we need more money"
