Of course we should question everything they say, especially if it affects the global population (like covid).

I always remember the movie mission impossible 3. For there to be a hero there must be a villain. They always create the villain to then present themselves as the heroes, the purpose...to amass fortunes, control and power.

They don't care if they destroy the environment or the lives of many people, the only thing they care about is their own selfish interests.
