Why did 'okies' migrate to california during the great depression,and what happened to them once they got there?

Explanation:

Domestic policy is a public policy under which rules can be exercised to all the members, citizens as well as foreigners, living within a specific territory or jurisdiction.

Every member and non-members who live within a controlled territory must follow certain rules of that territory. Thus, domestic policy can be compared to rules that apply to both the members as well as non-members of a club. In other words, "When in Rome, do as the Romans do."

However, once a non-member leaves the territory of a specific club, he/she does not become subjected to any rules of that club.
