Amid the coronavirus lockdown, Joe Biden is now running a digital front-porch campaign. In a video streamed from his home in Delaware on Monday, Mr. Biden said he would focus on “what we should do to get this response fixed.”

The remarks that followed weren’t encouraging. He characterized the Senate’s coronavirus relief bill as “a plan that let big corporations off the hook,” and “a $500 billion slush fund for corporations, with almost no conditions.” This rhetoric about slush funds is straight from the antibusiness left.

Does Mr. Biden not understand the problem that companies are facing? They have to figure out how to remain solvent until the health crisis ends, otherwise nobody will be left to turn the lights back on. Under Nancy Pelosi’s coronavirus bill, companies that take federal aid would be put under a permanent $15 minimum wage. Adding such strings to emergency funding will make businesses reluctant to accept the relief, even if they really need it.
