For me a child's gift from God, while the economy of God's possessions.
Meaning: The child is obtained from the marriage can be interpreted as a form of generosity, dedication, responses to prayer to God to the individual.
Economy: Assets that God's entrusted to individuals to be maintained, cared for, stored or conveyed to others.

Meaning: Two things children and wealth have different lines of travel, sometimes this human is tested given by children but not wealth and vice versa is given wealth but not given children, this process is like day and night.
If it is rich in having children and poor do not have children, it means that the world is unbalanced.
Example:
In the company there are 1000 employees who work mostly poor people, if the poor do not have children automatically the rich will die no one works, The rich child does not want to be a laborer or other person's employees, he thinks his parents are rich and vice versa so all of this hangs with each other.
