Gambling is not necessity, it is just an optional task which can be avoided if you do not have money to play it. If you can't afford it, there is no need to play it with money which is used for running the household expenses etc.
is just enough for allocation of those important things then using it on gambling would really be a very vary bad idea because you are putting yourself and family at risk.
Those people can even spell "dumb" themselves, but what pushes them to spend their income intended for living expenses and insurances is the little faith about winning and the potential to multiply the capital. Financial problem arrives after lossing all the capital in a casino. This scenario is very common, and I dont understand why gamblers keeps repeating the same mistakes. Maybe, not all the time ends with negative results, but it doesnt make any sense even if they win, because gamblers will always be gamblers.
