So the sucker here is the bank? Can't say that I care that much about that. It's just business and the banks apparently suck at it. They can foreclose on the business and sell it off to someone who relaunches it.
Don't the banks just print the money when they lend out anyway? Before the loan the money didn't exist. I suppose the bank is still holding the bag for the unpaid debt.
Some mortgages and credit cards end in bankruptcy too. They set their interest rate according and it is a cost of doing business.
