Too many people just know the govt is a big household that spends income called tax or borrows money like they do. I mean it's just obvious like that the Sun goes around the Earth.
While it is a basically immortal household but the same economics are at work.
An immortal household with access to unlimited cash that it can print at will.
So the economics at work are the same apart from being completely different in most important respects.
There are times it's worth borrowing--to obtain an appreciating/value producing asset or in dire circumstances. Other borrowing is no better for the government than it is for the household.
Governments don't have any financial constraints on their spending. They can spend as many dollars as they like, without earning, borrowing, begging or stealing them from anywhere or anyone.
Governments spend on whatever they want, and then later on, if they feel it is warranted, they recoup some of the money they spent, either as taxes, or as loans (typically bond sales).
They are in EXACTLY THE OPPOSITE position to a household, where one must first obtain money, by some means (earning, borrowing, begging, theft...) and only then are able to spend anything.
This is no minor distinction.
A government that spends without doing much of anything to obtain at least some money in return from the economy will run into all kinds of problems, for sure.
But a household that does the same is a physical impossibility. Because households cannot create money from nothing, and governments can.
