There is nothing political about it. Here's what happened. The inflation we are now seeing is a unique form of inflation that America has never seen before. It's not caused by rising wages it's caused by scarcity and the profiteering that results from it. If you don't have an oversupply of anything you increase the price of that which you still have. Here specifically is what happened to battery pricing. AS MENTIONED, this is an oligopoly. When you only have two or maybe three suppliers and there is a sudden explosion in demand the price goes up. Well, why was there a sudden explosion in demand? Answer: COVID-19. When this was at its peak a lot of people parked their cars for an extended period of time. Nothing is worse for a battery than non-use so many a good battery died an early death. When things loosened up there suddenly was a massive demand for replacement batteries and only a few sources from which to get them. For a while even finding a battery was a major challenge. Well, with red-hot demand and limited production capability any reasonable capitalist is going to bend you over which they most assuredly did. In a year or two things will once again reach steady state where supply equals demand and prices will drop, but not to previous levels, the chip shortage caused the same situation in car prices. How the hell can used car prices increase 43% in one year’s time. Simple, production is down and demand is up. Neither Trump nor Biden can or could control any of this.
