I agree that availability of gambling nowadays can be a very strong point when comes to an increase of youth gambling, but there are other factors as well, which we are not supposed to ignore. For example, neglected children are more likely to engage in activities like gambling, alcohol consumption and drug abuse. So, instead blaming all this onto the easy and legitimate access to gambling, we are also supposed to take a look on problems regarding the strength of couples and child protection, in general.
Keeping an eye on their online activities is one of the core things Wich are supposed to be done, in order to prevent kids (not only from falling pray of gambling addiction, but other harmful things, like pornography and internet predators) from encountering bad stuff.
Though, unfortunately there are parents who do not even care to look over their children and even gift them a phone while they are toddlers, so the chil stays distracted. The internet ends up being the education of the child, instead those loving parents.
One must wonder, how many children are gambling right now with the phone given by their parents.
