What? Being irresponsible is how the gov't wastes $ by spending and spending out of control (and the reason why inflation is so high).
The ONLY way to deter this mindset is to reduce the tax take so the smaller pile of $ forces the government to budget for less (or what Milton Friedman says, 'plus what ever they can get away spending' into a deficit). But don't take my word for it, most people don't have an understanding of macro-economics:

and to reinforce what Mr Friedman (may he RIP) says, 'that congress (or in NZ's case our gov't)
will spend everything they can get their hands on... and then some"
