It is not our responsibility to help the poor but we can do it voluntarily out of love. If it is necessary to help a poor family, then I will sacrifice my one-month gambling habit to help them. I could stand and continue with life even without gambling but it will be hard for me to see a family who is suffering because of poverty. That will not solve their problem but it could ease their suffering.
In a simpler context, the poor are people who do not have a job at all and do not have the ability to meet basic needs that are proper for the life of themselves or their families. In general, it is not our responsibility to help the poor or neglected children because they are the responsibility of the state or in other words (the poor and neglected children are cared for by the state).
The government holds full responsibility for them, sustainable handling is needed in the form of policies/programs and empowerment activities as well as facilities to meet needs such as work, health, education and decent housing.
We can only help to the extent of our abilities, sacrificing gambling habits can only be done once or twice, then we also have our own responsibilities to our families and include our own needs.
