Some of them provide excellent value in the form of customer service and support, and many package items together to provide entirely new products. I have no problem there, either. The problem I have is with companies that do no manufacturing or value-adding of their own, but simply buy items at wholesale prices and sell them at retail prices. Even importers provide value by dealing with customs and other restrictions that the average consumer does not want to have to deal with. A company can also distinguish itself for a while by having unique product lines like porcelain Alexander Hamilton figurines.
Fashion is fickle, and style quickly becomes stale.
Companies that repackage other companies clothing have to expend a lot of effort to stay on top of the market, and that effort costs money. That money needs to be taken out of the price of the products we buy, and so we get high markups. Companies that provide no inherent value of their own often rise and fall quickly, turning into an overnight success and then a distant memory within a very short amount of time. I know it isn't easy to come up with an idea that nobody else is already using. I also know it isn't easy to get started with any business, and it might seem like I'm down on business entirely.
