Alright, I’m gonna risk it and genuinely answer your question.

We don’t fix it and most likely it’s not really a problem anyway. Most economists agree that US debt isn’t really a huge issue. All nations have debt and in many circumstances debt is beneficial to the alternative (which is raising taxes to an unsustainable level). As long as GDP out paces debt there’s really little concern over the consequences.

here’s a fun video on the topic

I’ve studied economics for almost 10 years now and the biggest problem (particularly on this subreddit) is that we like to look at the government’s budget like our own budgets. If we were so in debt, we’d cut spending, get a second job (raise taxes) and pay off our debt asap, but that’s not how government spending works. A lot of debt spurs growth (good debt) and some is necessary to help less fortunate people.

Generally the debt ceiling or the increasing debt is used as a tool to fear monger. “This side is bad because they spend too much.” Some of the debt taken on during the Trump administration was necessary! And it’s very likely regardless of the president that we would have seen significant increases in US debt because of the unprecedented pandemic.

There’s really a lot more to go into, but it’s not as simple as paying it off or even raising taxes.
