It's just because they don't know, they don't have the knowledge of it so it takes someone to tell them about it so they can have that knowledge, but to most of them they are addicted to it and it can only take the grace of God for them to change automatically.
you're right on this, you know as a student savings won't come across your mind if only someone talks to you about investing. And even if someone or a friend introduce with anything concerning investment you feel like he doesn't want you to enjoy yourself, and when it comes to addicted most of the students started that lifestyle of burning smoke while they're still at home, and with that freedom of no one is here to control me any longer so they can smoke more then 5 pack cigarettes in one day. And a pack cigarettes is $30 for a pack but if they really had the knowledge of investing the money, I think before their graduation they might have gotten up to $25,000 or more than this before they're out from school. So what's killing the youth's nowadays it's lack of knowledge and not ready to learn about anything.
You may not think of it before but you will now, once someone talks about it to you. We still can enjoy life even if we are investing because no one is forced to invest all what they have. Even if we say one will do, there is a chance that they will earn a huge profit in the future and they can enjoy their life much better. We must be glad when someone approaches us for this. It only means that those people are concerned with us.
The addiction example you shared there is scary. If we prioritize our enjoyment over more important things, then there is a high chance that we will end up like that. They won't become an addict if they are not ready or willing to learn anything. It also means that they did not lack in knowledge but they think other things are boring and takes time to achieve.
