Economies are not zero-sum environments. They can expand to infinite breadth and depth so long as people produce things other people need and want.
Governments do not share this attribute. They exist only because they claim a portion of what others produce in order to sustain their functions. If they claim too much the producing class stops producing because it either becomes too expensive or the incentive is destroyed. This is turn folds back on to the government which now has even less economic activity available to levy taxes against.
One way for governments to be prodded into levying too many taxes is for citizens to demand additional services beyond the enforcement of civil order and public safety. As the services assumed by the government expand it must tax more. Worse still, the more services the government provides the harder it becomes to dislodge it once it becomes too burdensome as it will have either assumed so much pwoer it can retaliate against efforts to curtail its operations and/or the citizens have become so dependent upon it they will unduly suffer and thus be reluctant to demand reform.
Eventually, the government has become expansive it must levy taxes that stifle economic growth and in turn it will have less revenue potential.
As the spiral begins the original functions of government--public order and safety--will suffer because people will respond more immediately to having their home heating oil subsidy cut than considering the consequences of some abstraction such as being the victim of a crime.
To wit:
Cash-strapped Topeka, Kansas, has decided to stop prosecuting domestic violence casses [sic] in order to save money.
The City Council announced the proposal Oct. 4, after the Shawnee County District Attorney's office announced it could no longer prosecute misdemeanors, including domestic violence cases. The city's maneuver may even require repealing the part of the city code that bans domestic battery. Mayor Bill Bunten told the Topeka Capital-Journal city officials take domestic violence seriously, and it would be "dead wrong" to assume offenders won't be prosecuted. But the dispute is over who would pay for it, he said.

This is social justice, after all.
