Don't be obtuse. Of course you can spend more money without buying better craftsmanship. Some trainers from Prada or Balenciaga will wear out faster than a pair of Aldens.
Consider school backpacks. If you can, you should probably buy a Tom Bihn backpack. It's $400 and will last for decades. Spending more money will buy something fancier, but it won't be better at being a backpack. If you don't have that much cash to drop? Jansport, Eastpak, North Face? They're all the same mediocre product made by the same PE group. And they're still not cheap.
