I don't want to be defending MacDonalds or any other oppressive, politico-global, trans national, culturally homogenous capitalist neo-whatever.
But the point of an advert is to tell people that this product will fit in with your current lifestyle and enhance it.
Adverts are intended to sell products, so the company can make profit and employ people.
A few years ago, I was in a large factory making cosmetics, for various reason. In the distribution room there were hundreds of people, young and old, male and female, packing these products into little boxes then larger boxes. They were all working for minimum wage. All around were posters of various glamour models living beautiful lives.
It may sound like an obnoxious irony but in reality, those models were selling those products so those people could be employed. All were part of the team.
That is reality.
