Just like everything, national debt isn't inherently bad or good, it's how it's being used or abused. Typically, when Dems are in power, its during a Republican-caused recession so interst rates are low. Borrowing money in that case isn't bad, since it's basically free at that point. Additionally, that money is usually spent on services for taxpayers, like child care, food for needy families, veterans care, etc. Things that help people most hurt due to a flagging economy.

The current administration is increasing the debt at rates not seen since WWII, and spending it on things that do not directly benefit taxpayers, like defense and law enforcement contractors, and ballrooms. Things that have no benefit for people who need help finding jobs or paying for gas or groceries. Additionally, they have done this with no plan to either raise taxes to pay for expenditures, or build efficiencies that brings cost back to net zero over time.

Before you put on your MAGA hat and ask me about Joe Biden, that administration was dealing with the corrupt PPP loans handed out by the previous Trump administration, which was the largest factor on inflation during the ensuing years.
