It is easier to get money to get re-elected (bribes/donations) if you spend money on companies. So you buy military gear and give huge tax cuts and build interstate roads. But then, you need to get elected again, so you repeat. Eventually, you start spending more and more on this that are not really trackable like military and tax cuts and you can’t cover the cost of running the government, but you get re-elected. So you borrow and just keep repeating. You pocket the bribes. You don’t care if the country is broke because you are rich.
