More signs of a Peter Pan society

How it is reflected in the market the fact that many people still live with their parents beyond their 30th birthday, want to have a 'living apart together' relationship, or just prefer to lock themselves inside their room and play, play, and nothing but play?
How about this:

• adult designer toys and flashy apparel that can sell for up to few hundred dollars
• parties full of people well beyond their 'young-adultness'
• Hollywood movie blockbusters based on comic book characters
• entertainment where protagonists behave like 8 year olds
• ...

It strikes me as very ironic that such things are becoming so popular and so mainstream right when population is becoming older and older, and some experts even advent the coming of the Gerontocracy!

What will happen once the baby boomers and the 'silvers' decide to exercise their purchasing power? Will all companies start to look at them instead of the Peter Pans? Will we finally see pimped street golf-carts in our streets driven by young lads with pink shorts and white-dyed hair?
