When you think of trends, you tend to revolve around the idea of fashion. Trends are usually conducted by celebrities/wealthy.

Once these trends are made and established all over social media; the society starts to follow those trends.

Think about the latest fashion trends… What’s in right right now? I would personally say bomber jackets, ripped jeans, Stan Smith Adidas and etc. Those were all items placed out by very famous artist, which are mostlikely sponsored by these brands that we wear. (Celebrities are usually wearing these items for free and making money out of us because we’re following behind them. However we’re buying/purchasing these items.)
Here is when we start establishing the social structures within our own individual class. The people in our class that tend to buy these mainstream promoted materials, begin to feel themselves as ‘powerful’ and financially eligible as the celebrities. On some #youcantsitwithus attitudes.
This related to the Karl Marx’s theory once again.
According to the sociology expert, Nicki Lisa Cole, “He inverted Hegel’s dialectic, and theorized instead that it is the existing forms of economy and production–the material world–and our experiences within these that shape thought and consciousness.” Of this, he wrote in Capital, Volume 1, “The ideal is nothing else than the material world reflected by the human mind, and translated into forms of thought.” Core to all of his theory, this perspective became known as “historical materialism.”
