I think the author doesn't understand that there's a tier of disposable goods for just about everything and if you don't shop wisely you'll take some of it home.
Appliances for example: don't buy them from web pages and don't listen to Wirecutter. This is just letting marketers tell you what to buy. Instead go to a showroom that also repairs appliances. They'll know exactly which contemporary brands are crummy because they'll have been fixing them.
Specialty stores will also have the entire price range for the product so you can see what quality costs for that good. Marketers prey on us during times of inflation, making their cheap goods look high end before we adjust to inflated prices. If you've only ever shopped appliances at places like Target, Best Buy, or Home Depot, you may have never seen a high quality appliance in your life. And if a brand you like starts showing up in these stores, run. (Famously, Levi in Walmart.)
