Advice: this comment would seem far less aggressive, yet have its meaning unchanged, if you removed the words "have been trained to" before "believe".
These people have, using the media and effective control of government (the US's is basically an arm of Goldman Sachs), trained people to believe things that will harm them -- and everyone.
It's not a conspiracy, just a lot of disproportionately greedy people behaving to maximize the same thing, and to achieve the same goal.
