The problem is that gambling can attract people from various circles to try their luck, and this also includes poor people who want to try their luck. But those who don't have a lot of money cannot try gambling for a long time because there is limited money, and they have to be able to use their time as best as possible. If they still lose too, they will come back another time and that is what will keep happening over and over again. Those who try to make gambling a source of income will regret it after finding out that they have lost a lot of money and they cannot recover their losses. That is why we must be able to avoid thinking about trying to make gambling our main income because we will only have difficulty getting it, and in fact, we will lose a lot of money.
First of all, poor people shouldn't be engaged with gambling too often or spending considerable sums of money on it, respective to their total income. If they are gambling with the purpose of overcoming poverty, they have developed the wrong mindset for their lives. By doing this, they aren't having fun, which gambling is supposed to proportionate, neither making profit on long term, as most gamblers will always lose, anyway. So, it really makes no sense that poor people keep insisting in gambling. They would have better chances if they used their small income in another manners, like investing in Bitcoin or reselling stuff until achieving an enough amount of money to buy a piece of land or property.
By gambling continuously, the chances are poor people remain poor for the eternity. Of course there will be few exceptions who will hit big wins and leave poverty, and these exceptions will be used by the majority to justify the reason why they are gambling, although they still should be aware a life change is not going to happen to most of them through gambling.
