That's the exact same concept as a mortgage. But instead of securing the loan with the equity value of the house, you are securing the loan with the cash flows of the business. It's hard to see what's wrong with this.
In an analysis of "European companies around their buyout event in the period 2000 - 2008," private equity was found to "select companies which are less financially distressed than comparable companies prior to the transaction and that the distress risks increase after the buyout" [1]. Critically, however, "the distress risk in private equity-backed companies does not exceed the distress risk in comparable companies three years after the buyout," and, "despite this risk increase, private equity-backed companies do not suffer from higher bankruptcy rates than the control group."
More broadly, an analysis of "17,171 worldwide leveraged buyout transactions that include every transaction with a financial sponsor in the CapitalIQ database announced between 1/1/1970 and 6/30/2007" found bankruptcy rates around 6% [2]. This isn't exceptionally high.
That's an asinine comparison that completely ignores the underlying economic substance of the transaction. You can't pay yourself fees from a mortgage.
