As Congress debates what to include in the next stimulus package, the key to fixing the U.S. economy is fairly straightforward, economists say: Get the coronavirus under control. Economic recovery can only come if citizens feel safe.

Unfortunately, "straightforward" doesn't necessarily mean simple, Michael Klein, executive editor of Econofact, a nonpartisan economic publication, tells CNBC Make It. A disjointed and unreliable federal response to the virus has exacerbated not just the virus itself, but likely the subsequent economic downturn as well, says Klein.
