There is certainly a usefulness in separating government spending and private spending in our economic health measures. For one, measures like GDP are often used to evaluate the confidence and the general well-being of our economy. High Government spending tend to indicate the opposite, as Keynesian economics would mandate. More so, it invite manupulation of those measures by politicians, who can increase deficits to boost their "success". When it comes to spending like Education, those should be fairly constant relative to the population, in a developed country. We also have other mechanics to discuss their health status since they are largely public funded and subject to political debate. Perhaps a good measure would be the GDP minus public deficit minus credit card debt increase.
