Good news! You don't need to "prove" the correct answer on Main Idea questions in RC. Instead it just needs to "most accurately state" the main point.
That said, I still think we can justify the difference between the economists' definition of prosperity and our ordinary conception of prosperity. In lines 51-53, the author discusses the distinction between the economists definition of prosperity and "real" prosperity. It doesn't say that real prosperity is our ordinary conception of this notion, but it's close!
Lets look at the incorrect answers, which you said you could eliminate through process of elimination - another good reason to say that answer choice (B) is the answer choice that most accurately states the main idea.
Incorrect Answers(A) is too narrow in scope. This is evidence for undermining the critics definition of prosperity.
(C) is unsupported. This is a hypothetical not addressed in the passage.
(D) is unsupported. The critics simply say that prosperity needs to include other factors beyond easy-to-calculate values.
(E) is out of scope. This passage is not about predicting future economic prospects.
