All of that distorts the market and makes everyone spend money they don't actually have. Eventually all of this catches up with everyone, on a country-wide scale.
So much for all that personal responsibility we used to hear so much about. Far easier to blame the government for everything.
Companies use credit to buy back stock because we deregulated that activity. It used to be that the government didn’t allow it. This point is actually a counter-point to your theory.

For example, let's cherry-pick the Clean Air Act and its effects: "In addition, because air quality across the United States improved; it is estimated 205,000 premature deaths and millions of other respiratory complications were prevented which resulted in an economic savings of $50 trillion versus the $523 billion invested to meet the Clean Air Act standard."

Few would doubt the rise of the "working homeless" across the western world. The concept of someone having a fulltime job and still not able to afford rent is new. It is today's sharecropping imho.
And then there is the other modern phenomena: the legally mandated homeless. Every large city in the US now seems to have a bridge or overpass filled with people who are not legally allowed to live anywhere else. Stringent limitations on where certain convicts may live is also new.
Does that happen anywhere outside of San Francisco?
Alternatively one might argue that what is happening is a kind of bifurcation. The wealthy and well measured get an ongoing expansion while the poor, shiftless, and unrecorded fall through the cracks at alarming rates. We didn't have homeless families in significant numbers when I grew up and now they are pervasive. That is pretty poor real performance for a best ever economy.
