How does the gambling affect the society? 
Gambling is properly playing games of chance, 
such as cards, pitch-and-toss, etc… for money. 
But it also includes betting, which is staking 
money on an uncertain future event, such as a 
horse-race. The essential feature of gambling and 
betting is the risking of money on a chance, in the 
hope of winning a large sum. 
Moralists always denounce gambling as wrong, 
and yet at first sight it is not easy to show why it is 
wrong. It is true that in a game of chance or a bet, 
one of the parties must lose his money, but the 
gain of the other cannot be called robbery, 
because both parties willingly agree together to 
run the risk. You might say that if two sensible 
men agree to risk the loss of their money in a 
game of chance, it is their own business, and no 
one has any right to interfere with them. Perhaps 
a comparison of gambling and dueling will help us 
to see why gambling is an evil. In a duel, as in a 
game of chance, both parties willingly agree to 
run a risk. In gambling they risk the loss of their 
money; in a duel the loss of their lives. But in most 
modern civilized countries, dueling is a crime in 
the eye of the law, and is punishable with heavy 
penalties. Why? If two men agree to try to kill 
each other, that is their own private affair. Why 
should the law stop them? The answer is that it is 
not their own private affair. It is a public affair; 
because, if every citizen can take the law into his 
own hands and avenge an injury himself, all law 
and order in the state will go to pieces. And 
gambling is condemned for the same reason; 
because the effect of gambling is injurious, not 
only to the individuals, but to public social life. 
The evils of gambling may be summarized as 
follows. First, it discourages steady habits of 
industry by holding out before men the hope of 
getting rich quickly and easily. Secondly, 
gambling often becomes a habit, as strong as the 
drink craving, which a man cannot break; and 
frequently it leads not only to his ruin, but to the 
misery of his family that depends on him. Thirdly, 
it produces an unhealthy and restless excitement 
in men’s minds. Lastly, it often ends in theft and 
embezzlement, and even crimes of violence. 
Judged by its effort, it is therefore an evil.
