Your post has nudged me to think of what can be done to make gambling more productive regarding the education. As we all know, there are movies from which we can learn something and there are those intended purely for entertainment. Although we can't be learning all the time and that's why we need the gambling as it is now, to have an opportunity to relax from hard work or from studying, we still can sometimes combine the latter with gambling. Imagine if there were a site where you can learn English, for instance, while gambling. I think such a site could become pretty popular.
