Warren Buffet and Berkshire Hathaway absolutely benefit from borrowing money.
I'm going by something he said himself at a lecture. He said this when he appeared with Bill Gates back at the time when he gave a lot of money to the Gates Foundation. He said that many/most business borrow money to cover operating costs & cash flow fluctuations because of the tax write offs. So, you'll have to take it up with him.
Another snippet I found on the inter web: "Warren Buffett is stating the basic principle that you do not need to use debt to get rich if you are intelligent. All debt does is increase your risk, while if you are a smart person, you are going to make a lot of money either way."
Also, "At the same time, however, Mr. Buffett has credited much of his success to the float generated by his insurance businesses at Berkshire which is a sort of free leverage. Additionally, his company and/or subsidiaries have also taken out long-term debt.".
Regarding avoiding bankruptcy which is why Buffet feels strongly about using debt leverage to get rich - "He does this at Berkshire by keeping a cash hoard of tens of billions of dollars to ensure that Berkshire can always meet its insurance and other obligations."
