> Assuming price is one of the dimensions, this is generally a true statement. Otherwise we'd have a bunch of best-in-class products that are cheaper than inferior competitors.
You say this like it's an absurd condition but we can observe exactly this condition all the time, with new manufacturing techniques and labor practices creating better products for less resources all the time.
One place I love to observe this phenomenon is cars, where often even new inexpensive cars are superior in many dimensions to older luxury cars (including passenger amenities). But brand attachment and carefully seeded misleading advertising allows luxury vendors to keep their prices high despite a slower product development cycle.
