The Swiss Federal Council is setting aside billions of CHF (I think the total is currently at 32 billion) for exactly this: some relief for small and medium sized businesses. They've recently announced a process to have 80% of your salary insured up to a certain high cap, between 150k and 200k CHF.

There might be vastly different political and scale differences between the USA and Switzerland that make this infeasible for the USA. But Switzerland is showing that in principle it can be done. Making your blanket statement for the whole world, false.
