The reason that young people are going towards gambling is online gambling because they want big money for their future dreams and in the greed of winning more and more money they lose all their money. Nobody can stop them because they can gamble from their bedrooms. Their parents even dont know about their gambling addiction.
I know that young people these days are so intelligent and very matured than the past individuals but I don't think this is the reason why these young'uns are very popular or early immersed on gambling.
Internet is the reason. Internet these days are very popular to young'uns because internet are open to any people that can access it. With these young'uns freely exploring the internet, it will be a normal thing for them.
