Private equity only works because the United States dollar is no longer linked to gold.
Now, when the United States needs more money they can simply print it out of thin air. It doesn't have to be linked to a physical asset like gold.
This means our economy runs on high debt, high inflation, and an ever expanding economy built on a hollow stack of cards.
This allows private equity to skyrocket since their business model works because inflation always goes up in service of their debt.
Inflation always reduces the real value of your debt.
