Argumentum ad crumenam
An argumentum ad crumenam argument, also known as an argument to the purse, is the informal fallacy of concluding that a statement is correct because the speaker is rich (or that a statement is incorrect because the speaker is poor).
The opposite is the argumentum ad lazarum.
