Unemployment is getting higher over the years. And this is not even due to the lack of work in a particular place. Some people don't want to work the same way their parents did. All they need is to find money for food and not to be disturbed by anyone, after which they hope to win a big win in gambling without putting any effort into it. I don’t know how to explain it, they probably think that they are the chosen ones. The most important thing here is that they always need to look for money to play. If at the beginning they borrow from acquaintances and friends, then it can go even worse and the player will commit theft for the first time. Boundaries will be erased and at some point this will lead to very sad consequences.
Sometimes like you rightly stated, people are not unemployed because they are unable to secure a job, but most times is simply because the job isn't paying well enough or at some point they are bored with the job and want something else, several other reasons could be why some persons stay unemployed for a good period of time.
Some results to gambling because they think and believe that it's a very easy way to make money without having to stress so much and it avails them so much freedom with minimal working time, so these are some of the excuses that has kept some people jobless. Some literally have to forfeit looking for job and go into gambling full time and at this point they results in harmful habits such as stealing to fund their gambling activities which they wouldn't if they had gotten a job, they get addicted and even find it very difficult quitting.
