We often get so caught up in building up wealth and status that we forget about building relationships. People need community. In PNG, mutual dependence bonds people. Neighborhoods are strong. People know each other so well, parents can identify their kids' footprints.
Much importance is given to taking care of each other.
Wantoks help each other build a home. Wantoks take care of their relatives as they grow older. The wantok system is so strong there's no concept of an orphan. PNG society works because wantoks make strong commitments to their communities. And with all that security, upwardly mobile doesn't have to be for anything more than a coconut.
