The words are true that poor people think they will earn only because of luck without hard work and they find easy ways how to earn more in less time. The poor are more attracted to gambling than the rich and they think they can become rich overnight by betting on gambling, so they rely directly on gambling instead of trading and betting and eventually become bankrupt. But the rich do away with all these thoughts, they do business and invest in real estate, gold business, investment in banks, construction of petrol pumps, housing and infrastructure where they work hard and change their situation in a short period of time. But the poor stand against it.
Not all poor people are attracted to gambling, though some may be, especially those who are irresponsible. Since they are poor, they can't really afford to gamble, or if they can, they shouldn't, to avoid becoming addicted. Investing, not just in banks, may not be part of their thinking because many of them are struggling so much that they are just trying to survive.
They are not attracted but once their poverty level increases and so does their expenses and efforts, they are forced to have faith in gambling, instead of looking into investments, it is difficult for the poor to have enough attention to study an investable field like stocks, easier than real estate and gold but the question is they do not have the available capital. Gambling offers lower entry fees and when you are thirsty and have a huge desire to survive, dirty water can also excite you, this is a normal psychology but hopefully the government will increase supervision and limit this scary thing before it increases.
