In many industries and fields, speaking the truth isn't well-received because lies align with the beliefs of the masses and serve the interests of those in power.
I think the world can never be saved from the truth because it's almost in all industry and fields that manufacturers uses lies to fed us in a daily basis. If you take a look at the soft drinks aspect especially Coca-Cola, they had been feeding us with so many lies and the government keep supporting them allowing to keep telling us the opposite of the truth. If you also check the pharmaceutical industry, I think that is one of the worse industry feeding us with lies about the drugs we are taking which do have severe effects on us causing other future complications that will never be disclosed. This lies have been there for centuries and don't see any signs of it stopping soon.
