Giving money to businesses to keep people employed is a non-starter in the US as there is no political will to ensure those businesses don't just furlough employees anyway and pocket the bonus - will for both writing effective regulations and post-hoc enforcement against businesses that skirt them.
It also directly creates zombie companies if applied to industries that can't possibly bounce back, like travel etc.
IMO the appropriate business-saving economic response would have been to statutorily suspend all rent/mortgage/loan payments denominated in USD. That's the bulk of most small businesses' fixed burn rate. Needing to service the debt black hole is our primary source of inflexibility.
Of course given that we're still "debating" whether the pandemic is even real or not, figuring out what is appropriate is purely academic. Enjoy your token $1200 while the looters loot billions.
