This is stupid. Using this logic would be like looking at the US and saying they're one of the most poorly economic performing countries in the world when by GDP we're #1 by 4 trillion the last time I checked. Per capita, maybe top 10? The US has a per capita debt of 58,000 while Venezuela has one of 7,000, Egypt 2,000, Russia 2,000. Based on your logic you'd rather be in those countries.
Moderate debt is typically an indicator of a powerful economy. Look at the per capita incomes of U.S. states and the per capita GDP and you'll likely see those same states you listed above as well as maybe TX and FL.
Shoot, CA, NY, and TX, if countries, would be top 10 countries per GDP.
Even as an individual we take on debt for all sorts of things: car payments, mortgages, etc. Prices are typically higher in those states you listed compared to poorer states that are typically led by Republicans. On the other hand, the wealthiest states are typically Blue, and no I don't think D's do better than R's or R's do better than D's, the business cycle is cyclical so it's really the luck of the draw in terms of who is in charge.**
Markets recently have performed better under Dems but 30 years ago and prior it really wasn't the case. Even the economy did well under 45 until Covid messed things over.
**minus tax cuts because those have always led to market turmoil
