Businesses don't just price gouge. They often expand their product lines or have R&D to come up with new products and that's more costly than just making the same shoe with the same materials for 40 years. Many consumers feel like "Why do they need to grow? Why can't they just make the product I like and I'll pay for it?" But the reality is that not growing is not protecting yourself from the future. For every product Quince dupes (and they have every right to do them and congrats on their successful business model), there is a brand with a signature product people stopped caring about, and if they hadn't spent the money to expand and try selling new products they may not have survived.
