I would definitely categorize the Joneses way of living as personal selling because of the fact their main goal is to embody a lifestyle and to not only sell but really live to sell.
The tactic the family uses is not rare at all today. It would resemble how brands use people who are promoters, influencers, and even celebrities to showcase their products even sometimes faking to like it to generate sales. Fast food brands and brands who may even be coming up use these promoters to make ads and paid sponsored videos to help get the product out there.
I feel that the family is unethical in their approach of selling. I do feel that playing into this facade of a perfect family to generate sales is pretty unethical. I do believe other than that the family is very smart and skilled in how they sell.
If I was friends with the family before, I found out their secret, I would just be surprised and would just want to know why they never told me. Afterword I wouldn’t really be mad or anything just a little disappointed that beings’ friends was a just a step for them to sell products.
