As far as I have seen, in federal politics, the majority(left and right) spends, while taxes in general have not been significantly increased or decreased(percentage). What you are talking about is their rhetoric, which may be rhetorical itself.

What does change(and is more important) is Debt/Revenue:

The ratio is looking like it is trending in the right direction. If GDP decreases while nominal tax receipts increase, GDP does not change the debt, while the debt/Revenue ratio looks good for paying bills, while not boding well for economic health.

What is this "real world" you are referring to? There has to be a balance between current and future expenditures and economic health to facilitate these. Nothing exists in a vacuum.
