When I first started gambling I won gambling for several days then I thought I would earn a small amount of money from gambling every day. After several days I made some money like this and suddenly one day I lost all the money due to excessive greed. I understand that gambling should not be overloaded and that gambling should not be taken as a profession. Gambling is fine for those who can take gambling as entertainment and those who gamble for money should stay away from gambling.
The way I see it is a little bit different here, fine, gambling can be better for those who are gainfully employed, after all, they will have more money to gamble and perhaps the instances of their losses will not affect them so much compared to those who are just struggling financially and still gambling to lose. But one thing I will not so much agree with is the fact that being gainfully employed will stop you from gambling more or wagering higher. What I see here is greed, nothing else, and it is until you curb or control it, you will never be healed of it, not even if you have more money, it will only push you to risk more. To think it my way, look around you, you would discover that many people are gainfully employed but still gamble more, while some are not so financially buoyant, yet they limit their gambling activity because they are contented and are wise with it. This shows that anything about gambling is not rigid for all persons, it's about individuals in this context.
The point is that gambling is more recommended for those who do have a job that produces in the real world, none other than because by having an income, the defeat of gambling will not make you experience too much trouble, because by having an income, at least you still have a number of budgets from your monthly salary to make ends meet. In the sense that gamblers who do not have a job or are unemployed are not really recommended to gamble because they do not have the income to finance their gambling activities and the fear is that it is very possible for them to take out a lot of loans or even commit crimes just to gamble.
But on the other hand yes I understand what you mean that having a job is not always a favorable situation, because however gambling can make you lose more money when you treat gambling in the wrong way or approach, simply put whoever you are rich or poor you still have the possibility to end up poor when treating gambling in the wrong way, it will be very likely to happen when you are not able to control yourself. The point is that whoever you are, whether you are rich, middle class, or even poor, in the end, applying all limits and self-control must always be applied to your gambling activities.
