I would have shut the borders down sooner and been more vigilant on the testing and who was at risk. PArt of this damn thing was the panic it created and not the people that died or got sick. If we manged the panic, then things would have been better.
2. Race Relations/Mass Migrations
Can we all just get along? lol... There is nothing you can do with God's people. It is his will to change, not yours. If some douche bag hates a Chinese man, for being slanted eyes, there ain't much you can do about it. You just have to ensure everyone is safe, both physically and economically. Everyone must have a chance.
3. National Debt
Spend that money man. Spend that money. We won't take it with us when we are dead. Just try to ensure that all industries remain open.
