Earlier quoted context omitted.
Only the part that went into the payroll. So a business owner with no revenue borrowed money he did not need and got saddled with the payments. Oh, and as the vast majority of the loans it is personally guaranteed. Compare this with: Don't get the loan. Shut it down. Not owe more money than the owner would owe already.
"Only the part that went into the payroll" why else would you ask for the loan? the whole point is to keep employees on the payroll while they're under shelter-in-place orders.
This means that by taking this loan and spending it on a payroll for next 2.5 months, the owner of the business in a month number 3 is in a worse position than the owner of the business would have been today if the owner were to simply lay off everyone.
The only winners in this are banks making a percentage of a zero risk loan that can be serviced at an incremental cost of a couple of dollars (electronic payments). It is, frankly, disgusting that the congress yet another time took small business loans as a base and made it a money stream for banks.
