start with understanding this
if everyone (people, businesses, gov) would only use money they earn vs money they borrow from someone, than you would be right, but thats not how the world works and therefore we are in deep sh*t right now as more and more people are complete deadbeat junkies and in turn their work ethic and decision making process is garbage, then you have gov spending out of control, in part because more people rely on gov in park because of corruption.
think about those points, books where written on these topics, and we are watching history in the making right now.
