Moral Issues
One of the virtues in American culture is to help others.
Christmas in America means different things to different people. To some people, Christmas means brightly wrapped packages under a decorated tree. To others, it means family reunions and a wonderful meal together. Christmas also means lending a helping hand to people in need. Along with all the hubbub of shopping for presents and sending Christmas cards, many people in America take time to help others.
In America and around the world, Christmas offers many opportunities to spread "Peace on earth, good will toward men". For example, Salvation Army bell ringers are a familiar sight to most Christmas shoppers. They stand outside malls and stores collecting money for the needy. Many churches and other organizations collect toys and clothes as Christmas gifts for poor families. The Christmas spirit encourages people to help each other in many large and small ways.
