This has been tested, many times over, and I have yet to see convincing evidence this is the case. In fact, despite this industry being on the scale of trillions of dollars, I bet you have also not seen convincing evidence of your statement.

Because those trillions of dollars aren’t going into research (well they are, but not into good research) it goes into propaganda, and this is one of the lies the industry tells people. The industry tells this lie so often that many people have started to believe it, just because they herd it so often it must be true.
