我真的不明白第一句话

Products sold under a brand name used to command premium prices because, in general, they were superior to nonbrand rival products.

说的是有brand的比没brand的贵，而且，比没brand的好，对吧。

但是后面又说，于是，
As a consequence,
brand-name products generally neither offer higher quality nor sell at higher prices.

brand-name products既不比普通的质量好，也不卖的高价。

这不是自相矛盾吗？
