Businesses, many of them, have expenses they have to meet whether they open or not. Taxes, debt payments, minimum upkeep for their properties, pensions, etc. In many cases they need cashflow to meet these obligations month-to-month. A month off will leave them desperate and many will not be able to reopen. Two months off and that number of permanently shuttered businesses will rise exponentially.
The people being shut down have a legitimate point that if they’re going to be forced to stop earning income, their landlords, loan officers and tax collectors should also be forced to stop collecting income from them. The shutdown should not be a one-level deal where only the people at the back of the food chain get hammered.
