I apologize for the oversight. Upon reevaluating the examples provided, the best instance of snob appeal propaganda is actually:
"If you vote for me, I promise to make your dreams come true!"
This statement suggests that by voting for a particular candidate, individuals can elevate their status and have their aspirations recognized and fulfilled, which is a form of appealing to one's desire for exclusivity and higher social standing.
However, the original example I mentioned does contain elements of snob appeal too, as it associates the product with the lifestyle of a celebrity.
To clarify, both statements can employ snob appeal in different contexts. But typically, snob appeal focuses on exclusivity or associating oneself with a higher status. Thank you for your patience!
