Basically, the role of the government is to provide for our welfare, to see that we flourish, etc. Note this part of the constitution:
We the people of the United States, in order to form a more perfect union, establish justice, insure domestic tranquility, provide for the common defense, promote the general welfare, and secure the blessings of liberty to ourselves and our posterity, do ordain and establish this Constitution for the United States of America.
Notice that from a GOP perspective even public schooling is anti-American in that it wasn’t guaranteed explicitly in the founding documents and it’s inherently…um, socialist. Are you against public schooling?
The same goes for public fire departments and police departments. It’s quite socialist to rely on other peoples’ tax money to save YOUR house when there’s a fire. Yet both public schooling and public safety are plainly good for America. Why? Because they improve the quality of life of the general population. See again the “promotion of the general welfare” above.
