Let me give a try. Assuming Parent is Resource & Husband (son) as DM.
DM has wealth and is favorable to him. Thus, husband was able to marry a productive wife that helps him gain Authority which leads to the creation of Resources. These Authority and Resource toward the husband is actually wife's Production & Wealth. It is wife's effort that leads her to produce wealth or another way to express: control Resource for husband.
As stated, husband's Resources are his parents, since the parents probably will know or maybe knew about the wife's abilities, they probably decided to let the wife control them because it is in their best interest for their son. If wife is not happy (Wealth) then son (DM) will suffer. Happy wife makes happy life🤩.
All goes well until husband/son decided to abuse his Wealth (wife) by cheating or having another affair (who knows why). Thus, Wealth (wife) becomes unfavorable to DM. Wealth may leave thus end of the story. Instead, wealth decided that DM should be punished and attacks Resources or stop producing anything for Resource😤. Without support, DM strength weakens or become unhappy (at least for the moment)?😰
