Poor people come to gambling not just to spend it for nothing, but their purpose is to grow it. And even middle-class and rich people do. And all of them still gamble despite the losing experience because they wanted to win. I believe we just consider this totally for fun if we don't care about our money.
We can't deny the fact that we are gambling obviously to make more money. We are considering this as an opportunity, but yes, a risky opportunity that can also ruin our lives if not controlled.
Rich and poor do have the same risk in gambling, although sometimes their goals have different goals in gambling so far, poor people, as you say tend to gamble to grow their money, meaning they have the desire to get big wins and can change their fate, while rich people, actually gamble for fun even though winning is still the target, But in this case we can compare the impact that occurs is also very significant for the poor and rich, because in fact in many surveys that exist poor people are more inclined to be trapped in addiction and even the impact they get is actually worse in terms of finances, compared to rich people who do have financial stability in their finances.
