I was in argument with someone. His view is that people who gamble are those that what they have is not sufficient for them and so they try to make more money from gambling. He said if you have sufficient money to take care of your needs that you won't think of gambling. He made reference to some rich people, who don't gamble because they have sufficient money to even gift to charity but that those rich who still gamble are only addicted to it not just because of the money. Therefore, that the percentage of the rich gambling is very small compared to those in middle class and lower class.
So my question is, is the percentage of the rich gambling lower than the middle and lower class?
Your friend is quite wrong for that. In fact, most people in casinos are rich people, but it's different from people from the lower or middle class, these rich people usually play gambling as entertainment or socialize with other players to increase their network. Especially in Asia, most of the rich people here play in casinos like in Macau, Singapore, Hong Kong, etc., because it's like part of the culture especially for Chinese people, you are not called a rich person if you don't gamble.
However, the percentage of rich people who gamble is much smaller than the middle and lower class, because there are fewer of them, so their percentage is lower.
