The truth is that products are made to make money for the business first and meet customer need/wants second.
For the dishwasher example, most dishwashers are far too noisy. Unless you live in a large place with many rooms, it will matter. The problem is that quiet isn't a highly visible/marketable and cheaply made feature, so isn't prioritized. After purchase, many would want a quieter dishwasher but very few will bother to uninstall/return/exchange it.
Most businesses make money by answering customer needs.
I actually believe that when shopping for kitchen appliances recently, dishwashers had a sticker advertising noise levels.
