It's none of your business if someone decides to delay. Maybe they just enjoy being a kid? God bless we live in a free country, not a military state. If market forces dictate that they need to grow up they will.
It is my business. Society is composed of people and we need people to grow up and take on responsibility. If that does not happen, we are all screwed, including all those that refuse to grow up. Making excuses for them and delaying the time does not help anyone.
