If the Social Media star that you are watching said: "Hey guys, I finally got a Picotin 18 (hey, it is cute and popular but I wouldn't do a prespend of a huge amount for this..just my opinion) after a five year wait and a million Euros in prespend! I am so excited..I really have a sweet and friendly SA who looks out for the things that I like..I will spend another half a million and buy more FJs and then I'd be qualified to get an all-black Rodeo Pegase Touch PM..wait for my next unboxing videos!"

How would you feel? Would that appeal to you? Would you buy more of that brand and feel that your "goals" are attainable? Would it speak nicely of the brand? Probably not?!
Therefore, they have to make it sound like a fairy tale..and there has to be a"Happily Everafter ending"

The more that a video is pleasing and gives a good feeling, the more followers it has..which translates to more money!
Not saying everything online isn't true. But if money and businesses are involved, a lot of factors play into that video content.
