This is also why I think Bitcoin rests on shaky foundations, and why I get tired of people who want a balanced federal government spending budget.
If the government were to optimize its net worth, then it would be pretty obvious that borrowing money to build transportation infrastructure and providing healthcare is "good" government spending and doing tax cuts or welfare is bad with debt. I don't know why but a lot of people pretend that governments are basically private households and all government spending is consumption.
Not all of it though. Giving an 80+ year old dialysis or extending their life a few months or nursing home care requiring round the clock staffing is not going to net any returns for society. A third of healthcare spending was post 85 years of age, as of data 20 years ago. Surely it has skyrocketed since:

Imagine these resources put towards children.
And fewer children will lead to even higher healthcare spending, since as far as I know, much of the tasks for elder care is not yet in the wheelhouse of automation, and it is highly undesirable work.
Conversely, creating more debt (as is with QE) adds value to everyone who has borrowed to invest. At some point though (usually through bankrupcy) this becomes inflationary.
It is inflation that steals value from producers who trade work for money: remedied only by demanding more money this is a vicious cycle.
Let's say I have a car that is worth $30k. I create a car coupon that lets you buy the car for $0. I have created more money without "stealing value".
Money is created by promising work in the future. Considering the huge demand for work in the future it should be pretty obvious why there is so much debt out there.
