Millennials are the first generation to experience diminished economic prospects compared to their parents since the great depression. So everything is going to take longer and be harder for them. With diminished prospects come delayed starting of families or the complete avoidance of them. That spells cultural failure for the west. I don't blame this on millennials, it's a symptom of worsening economic prospects.
Some millennials I meet seem incredibly entitled, immature, spoiled and self centred and others I meet are educated, polite, technologically savvy and way more together than I was at their age.
If millennials are living in their parents basement, it's mostly due to poor job prospects and unfathomable real estate prices. All of these factors are not of their own making.
Some millennials are being over indulged by their parents which is also not their own doing but it's something for which they will be disserviced.
