It's not. Heaps on heaps on heaps of small businesses have been destroyed by cheap international goods that Walmart and Amazon push, and customers have crappier products that don't last as long as a result.
This is incorrect. The products we buy today from the Chinese through big box stores like Walmart (or Amazon) actually last much longer and work far better than the same American-made goods from 25 years ago in those same big box stores before China was so dominant.
Quality is actually going up as prices come down VIA CHINA. You may get comfort pretending otherwise, but Chinese manufacturing is generally far better than US manufacturing at large scale. Sure, you can find some bespoke businesses that make great stuff here, but if you want the best possible smartphone or bluejeans or air conditioner, or automobille, you'd go with China over the US most days of the week.
