Laundering any "small" business help through the banks while not requiring those businesses to be small in any meaningful way ensured all the money would go to bigger companies. You don't need a big conspiracy to explain this, though bugs are often features, as the processing and oversight work for a $1 million "loan" is the same as the processing and oversight for a $10K loan, so the banks are gonna do the former first.
And round 2 will do the same. And none if it matters because every municipality in the country is going to be out of money soon.
