Diversity of ones sense of values ??

Some columnist say that people(especially young people)have many diverse interest so their sense of values are diverse. So the marketing to those people is very difficult,they intend. But I raise objection to those comments. I think that in these days especially young(including old young) many people do not read newspaper and technical(or specialty) books and cannot shape their own set of opinion and live style. So they do not have any solid interest or curiosity to anything.It is not diverse but there is nothing to be absorbed. That is serious problem.
