“Mr. Trump did not get where he is by stabbing folks in the back that are on his side. Ask any of his suppliers or sub contractors.”

Any business venture carries risk, except (usually) for W-2 employees.
If they don't want to take the risk, then don't sign the contract.
Bankruptcy is a business toll with the rules decided by g0vt.
