Japan's debt is over 200% of GDP, and no one's going ape s*** over it, so we have a long way to go. Besides, that debt is never going to be paid back. And it's why interest rates are being held down. We do have to pay to service the debt, and it eats a big chunk out of the budget. If interest rates ever did go back to normal levels the government would be in big trouble.
However, federal tax revenues have hit an all time high, so the Trump tax cut has worked. Even the rich are paying more.

And with all the baby boomers now retiring, 78 million of 'em, all wanting Medicare and Social Security, along with other subsidies, that debt is going to grow exponentially. So buckle up buttercup.
