When not hot is hot,
The poles of a magnet require two streams of influence. One pushes one way and the other pushes the other way. We then create a field of influence which covers all sides of the whole bar, the entire formation of magnetic particles in a group. Add more magnets and the field grows, the polar extremities are pushed further and further out.
In trends, niche culture and society in general, the extreme ends of a movement can be likened to these principles. Music is a big example, when one group releases one kind of sound, another group emerges to counter it, on the other side of the spectrum. Rockers and Mods perhaps were the first well publicised example of this phenomenon with the release of cult classic, Quadrophenia.
In this way, each movement splits into its polar opposites. Royalists and Cavaliers in all their many walks of life spring up in their many flavours. Then still, the groups split off once more into their purist forms and their more dilute and tolerant ones. It happens with music, religion, clothing, and even diet and nutrition.
The push of one trend serves to fuel the growth of its extreme opposite, in many cases. As pop music became more commercial and homogeneous, alternative music began to diversify to compensate. The resulting army of rock, electro and world music groups to counteract the ever growing pop music industry have been required, much in the way of a tight rope walker's stick, to keep culture balanced and flowing in the directions required for holistic growth. We choose what we want. We pay for the things that end up back on the shelves next year, as well as the media throwing everything it has at us to make us buy their particular thing. For all the billions spent on promoting one artist, it can take a mere image or a mention from a friend to actually make a sale for a smaller product.
This is how the alternative market grows, via mentions, underground media, and subconscious kudos for being brave enough to make an effort. The symbol of alternative culture is a trend on its own, and it speaks volumes about the mentality of the person who immerses themselves in it. We know that our thoughts about life matter a great deal to how w end up living it, and so when we allow modern culture to direct our vessel according to its wishes, what we choose to nourish ourselves with makes a big impact.
This perhaps means that having a balanced and whole rounded approach to culture is a good and fair way to ensure we do not tip too far to one side, and permanently change our direction according to the perspectives of the media around us. One trend will ultimately push us in their direction, and the opposing trend in the opposite one, so if we can find a rounded taste for many of life's pleasures and activities, styles and ways of doing things, it can be fair that we get a positive and spirit nourishing experience in daily life. This of course is required for personal growth, mentally, physically, emotionally.
