Eh. For many young people, this IS the "real world". These are their experiences. It's not productive to discount so many other people's realities.
Movies and movie conventions. Baseball cards and other popular collectibles. Sport events. Music events. All those things are just "corporate pseudo-cultural productions". Yet they're also the culture, because - for better or worse - commerce is part of our lives too.
And I am saying it is enormously productive and beneficial to be skeptical of those things.
