The answer to your initial question, “What does small government buy us?” is quite simple. It buys us a smaller economy. This isn’t ideology. It’s just math.
As the sole source of US dollars, our government’s red ink is the only “net” source of black ink the private sector has. In the end accounting, Congress determines the size of our economy by determining how much money is available to retire private sector bank debt and to net save. Our national debt reflects the money currently in savings (Treasury bonds) from past production, not a mortgage on future production owed by the private sector.
The US dollar is self-funding, meaning that it is available to Congress in an infinite quantity without regard to any revenue. When our economy is viewed in the proper perspective it becomes very obvious that our government “funds” our economy, not the other way around. The misconception that we fund our government via taxation or bonds is the most damaging lie in our history and is responsible for any misery that could be mitigated with money in our economy. The people will not be empowered to democratically direct their government as long as this grand lie persists in our narrative.
