Taking out a loan is okay, in the short term, if you have a plan to pay back your loan using income that you plan to obtain in the future but do not have available right now. THe US national debt has grown so large that the interest payments alone are like 20% of the federal budget, and that doesn't even touch the principal. It has reached pyramid scheme levels of borrowing, and no pyrmaid scheme can last forever. One day, lenders will lose confidence in their ability to get their money back and everything will collpase all at once.

In order to prevent that, the budget must be cut. People must be fired. Promising projects must be discontinued. The question is where to make the cuts and how, because cuts in the wrong places in the wrong way will end up making the problem worse. For me, working in healthcare/science/research, I see the cuts to the NIH spending as a bad cut, because it sacrifices a lot of future revenue from scientific R&D. Same with cutting USAID and losing a ton of soft power that could be used to persuade developing countries to let in American companies. Or firing, say, IRS employees, since they're the ones who actually bring in the revenue. So there are good cuts and there are bad cuts, but the point is that eventually cuts must be made.
