I was talking about some concepts, not gold diggers.
Let me repeat, highlighting title:

There are two concepts:
The right, and the misuse of that right.

Example1:
Bigamy in Islam:
The right:
A man can have more that one wife, on condition of treating them both equally and kindly
The misuse of right:
By unequal treatment, bad treatment, etc.

Example2:
Divorce in the west:
The right:
A woman is entitled to get half of the man's fortune.
The misuse of the right:
“Ah, yes, divorce, from the Latin word meaning to rip out a man’s genitals through his wallet.” –Robin Williams

Hopefully clearer now
