Passage Summary: The author claims that because inventors are just trying to get rich, the things they invent don't actually help the public.

Conclusion: Technological innovation is rarely beneficial to society as a whole.

Reasoning: The people who create technological advances are almost always motivated by personal profit and commercial success rather than a desire to help society.

Analysis: This argument suffers from a major flaw: it confuses the *intent* of the creator with the *effect* of the creation. Just because an inventor is motivated by greed doesn't mean their invention can't be incredibly helpful to the world (think of life-saving medical tech developed by for-profit companies). The author assumes that personal gain and societal benefit are mutually exclusive. Look for an answer that identifies this failure to distinguish between the motives of the innovators and the actual consequences of the technology they produce.
