For the ones that have to completely shutdown, the government would have to just give them the money they need to keep paying their fixed costs like leases, revolving credits debt, etc. Not enough to make a profit, but enough to stay afloat and get back up and running when we can truly open up again. And, of course, the owners who aren't able to make a profit would get a stimulus to allow them to feed and shelter themselves and their family until they can run their business again.
I don't anticipate a lot of businesses that can't operate at all if people would be reasonable in their actions, but that's really the rub. And, I think it's likely going to have to be done even if we follow a reasonable phase in plan.
