Thanks to larger companies buying up the little guy, the rise of synthetic fabrics, and the death of American manufacturing over time, the quality of many clothing products has cheapened in favor of larger production and profits. Whereas people used to buy fewer clothes that would last ten times longer, the fast-fashion industry now has us buying more clothes that aren't meant to last longer than a season.
Not only is this detrimental to the consumer, who is fooled into spending more money over time, it's also harmful to the environment. Clothes—especially ones made from man-made material, just don't decompose. It's also messing up the vintage market. All the quality goods from the 80s and before that are being scooped up, and in the future, most of today's disposable garms just aren't meant to be the next generation's thrift store finds—they're meant to be tomorrow's garbage.
