This is more a discussion of semantics than about the amount itself. The way I read the statistics is that the current debt is $28T of money that is already spent while the quoted debt of $146T is the amount of money needed to be spent to fill full current promises and expenses . It's interesting that since the USA got off the gold standard in 1971[1], and thereby all countries that had a currency backed by dollars,…
this is a good point. Everybody keep saying that US had a small inflation in the last 2 decades. Yes, prices of eggs/milk maybe didn't go up to0 much. But what about prices of child care, education, housing, health care, retirement. Yes all these have many factors behind their cost rise, but money printing just can't be ignored here.
Look at this post to see how many different measures of inflation there are. Each of these get at different aspects of the economy:

As for money printing. Per US law, money cannot be just printed by the Treasury. It must be borrowed from people who already had dollars to lend.
New dollars enter the economy when banks lend money; that is the main engine of new money creation, and it is responsive to the economy. Usually, banks don't lend when its too risky, and businesses don't borrow when it won't lead to profitable growth.
