Large families are socioeconomically poor to impoverished. Struggle, scarcity, & doing without even the rudiments are integral parts of large family life. Because of socioeconomic impoverishment, it is commonplace for large families to received outside assistance to keep them socioeconomically afloat & to provide them w/food & clothing. Large families are seldom, if ever, completely self-reliant. Furthermore, middle, upper middle, & upper large families are extremely rare. The overwhelming majority of large families are poor, impoverished, & even penurious.
It is simple mathematics the more children parents have, the poorer socioeconomically they & their children will be. There is LESS to go around. There is a saying that large families have less. When one grows up in a large family, h/she is used to going without. H/she is used to having an inferior quality of life, subsisting at the most basic & primitive level. H/she feels that poverty, want, & scarcity are normative lifestyle. H/she becomes used to this & is satisfied w/crumbs. As my late father stated that those from large families are used & happy w/nothing.
