I see it this way that money interest teenagers more at their time since most of them had so many things they want to have or do at that point and they find gambling easy way to increase their money in order to obtain those and that ends up pumping gambling addiction into them.
A winning taste and that's enough to pump addiction ...
It is also a factor that young people want more money for their needs and for this they choose gambling way. They think that gambling is the only way that can give them big money in less time besides they know the bad consequences of gambling. Gradually they become addicted of gambling and then the time comes that they cannot able to quit gambling.
That is the thing, and they want money they do not necessary have to work for. What even gets it all crazy is the mindset they tend to have which they usually bring into gambling in terms of wanting to get rich and make more money than they can imagine from gambling.
Now, thinking level will always differ when it comes to maturity, but in most cases, a lot of them would have been so deep in it, realizing the reality kicking in and then finding it hard to accept that reality until they get burned, grow with it, end up wasteful unless they eventually manage to get help. I guess there has always been a reason anyway for most casinos to have restricted gambling to a certain age, but unfortunately, the jet age has exposed more people who are not even capable of handling emotions into it.
