From each according to his ability, to each according to his need

This is a phrase created by Karl Marx to describe a society where everyone shares what they can and everyone gets what they need. In a society like this, everyone would work according to the abilities they have, and they would all share what they can and make sure everyone has what they need. So if someone is really good at sewing, they would share their sewing skills with the community and if someone else needed help sewing clothes, they could get help from the person who is good at sewing. In this kind of society, everyone would help each other get what they need and everyone would be taken care of.
