"Id do a better job , IF...... they payed me more."
"I'd treat my Husband/Wife better IF........ they were nicer to me."
Thats not how it works.
If you say to the fireplace. "Give me some heat, and THEN.. Ill put some firewood in."
You can see how ridiculous this sounds.
To be better paid,
better thought of.... GIVE FIRST.
The rewards come later.
