Why do some people have to have what's cool?

It seems like some people aren't happy with just the basics. They just have to have the latest iPhone, iPod, Beats headphones, designer clothes, luxury cars. Why can't people be happy with a TracFone, basic mp3 player, decent clothing, and a basic car like a Ford or Chevy?

Because they're doing exactly what advertisers want them to do, they're following what companies have arbitrarily decided is cool.
that makes them mindless
