In order to establish a healthy family it is necessary to meet basic physical needs. Nothing else can compensate for gaps in those needs being met and when they have not been met for a family it is difficult if not impossible to focus on other areas of need in building a healthy family. This is a concern that can be addressed at the level of individual families but also at a community level.
When we speak of physical needs in a prosperous nation like the United States we are generally speaking of financial needs because everything to meet our physical needs is generally available so long as someone has the money to acquire them.
