Maybe, but somehow their behaviour and their products and services changed. Companies are made of people, and individuals had more freedom to put value in what they did, they took pride in the quality of their work. After Friedman everything got "optimized" for revenue, even if this meant screwing the customers (or the society). There are some things that cannot possibly work with this "self-regulated" market, so if we want to accept this way of doing business, we should move back some responsibilities to the public sector (healthcare, infrastructures, rehabilitation, education, research), because the search for "immediate gratification" of shareholders can't move the society as a whole out of local maxima that are far away from society best possibilities.
