This is a repeat of the same claim regarding labor.
And even then there are holes in this position. Efficiency often won't lead to a wealth effect. In many industries (Buffett highlights textiles frequently, but it's also true of agriculture, many consumer electronics, cars) the competitive dynamic is such that increasing efficiency just lets the company stand still. Cars and TVs for example have become significantly better over 40 years(not all due to efficiency, but a good amount) and the prices haven't much changed, due to competition. The companies in question are still earning low returns on capital despite their efforts. I don't feel richer because my $600 TV is 60 inches v 30 inches, and I don't go spend more money because of it.
GDP has holes like this. It's literally just measuring end user transactions.
