The consumers will simply buy what is available. I haven't either. The speaker could have cited the Constitution or other legal document to prove his point.

Stockbrokers are experts on the economy.
The fact that someone has a job as a broker, however, does not automatically make this person an expert. The same is true for any occupation. A false cause fallacy is created when the speaker assumes that an expert is without flaw. We need to recognize that a job title does not cause someone to become an expert. All stockbrokers are not experts, so this is a clear stereotype.
