We rely on having money. And we rely on a mature economy where someone is willing to solve every problem in exchange for that money.
In an individualistic society, each person is expected to earn their own way and then pay to solve every problem they may have.
In more community-oriented societies, personal earnings are less important than a strong network of friends and family who can fulfill every need. Each person's income/wealth is contributing to the collective for whatever cannot be served internally.
This movement toward individualization correlates very strongly with the capitalism.
