I have been researching this topic for some time now and wind up with more questions than answers. It goes back to my primal instinct of following the money or who profits?
China was the only major economy that grew during this debacle. Politicians who took money or who had indirect ties with China gained power here politically. The masks and much of the materials came from China. The virus came from China.
I am not an economist, a doctor, or a foreign policy expert, I do know that whomever profits from wars, pandemics, terror attacks, climate change, and financial collapses are usually the perpetrators of these incidents, either directly or indirectly.
I forgot to mention the multinational corporations who profited handsomely while the middle class was devastated. Always follow the money to the truth.

I think you're pretty close to the mark, although I don't think there will ever be any investigations on anything tearing the country apart, and certainly they will never follow the money where it concerns people who have a lot of it.
