Please find out about Modern Monetary Theory (MMT). It explains sectoral balances, among other things. The idea of sectoral balances is that there is a public sector and a private sector. Since the government (the public sector) creates the currency, they have a different ability to withstand changes. The private sector has to rely on money (currency) coming into it from the public sector. There is an inverse relationship between the sectors: the more that the government spends into the economy, the less the private sector has to come up with cash. Similarly, the more "debt" the public sector carries (remember that a government can never go broke with any debt in its own currency), the less debt the private sector has to carry. Politicians and economists like Milton Friedman know perfectly well how this works, and they use the ignorance of the people to manipulate them. This is why they practice neoliberal austerity: they force the people (the private sector) in to debt slavery. You can learn about MMT on YouTube from The Rogue Scholar, Macro'n'Cheese, MMT Mondays, or Real Progressives. Stephanie Kelton also has some excellent videos on YouTube about it.
