My theory: the COVID vaccine was rushed (emphasis on RUSHED) because of pressure by big money interests who were petrified of an economic collapse if our society took the time to do actual safety and efficacy testing of the vaccines. It would take years, and our debt-ridden house-of-cards economy can only afford to wait “weeks”.

Big money in the US (and also western countries) would rather risk having horrific “adverse events” among the peons than risk losing money (bonds, stocks, commercial real estate, …)

As George Carlin once said about the oligarchs, "it’s a club … and you ain’t in it”. And to the oligarchs, anyone not in the club doesn’t matter in the slightest.
