in my country, those who earn less are most addicted gamblers,
its a simple logic . they are not happy with thier earning so they want to double thier money in the form of gambling but those who earn big are contented enough so they dont play gamble at all
every thing that they can get their hands on, they will simply put everything on the line, including online games.
its okay if those less earners will gamble only what they can afford ( ex. putting 1/4 of thier money as bets ) so its not evasive at all whenever they loose . atleast when they loose they still have some cash left on thier wallet .
we have a saying here, "One day Millionaire". If they won big, expect that it will be gone in just one day.
i have heard of that saying before . it goes like " one day millionaire , one month sustainer " the saying applies mainly for workers that spends thier salary only a day or two due to debts/loans , and other expenses while thier salary is small . but not all who win will spend thier money in one day .
