In magic, I find we have motions similar to a stock market. A bubble-and-crash is often caused by a sudden trend or overestimating the price, which shoots into unrealistic heights. It seems like everybody discovers it and wants to participate. Of course, the majority doesn't know exactly what they are doing. The masses going to the stock market, to get rich quickly.
In magic, I observe some trends too. So many all doing the same things. One copying the other. The great rush for the "newest" gimmick, trick, or routine. The problem then is that too many people are doing the same tricks. The result is that they search for "something different" (depending on other trends then).
The good advice is to research tricks that nobody does. Or, at least, tricks that are very seldom shown. Doing something because the others are doing it, or having success with it, is never the best decision.
In our literature, especially the elder one, are tons of great tricks that are forgotten, or never have been read by the majority of magicians.
Hidden gems. Go hunting for them and forget what the dealers praise as the newest and best.
