believable to whom, exooo? If you are a slave of money, then you fall to your knees like any other slave to anything else. What makes people "believable" is their character... tested over time with a few solid folks who will vouch for that character if called upon.
And btw. "society" is SERIOUSLY overrated.
Belivable for mister the average woman or man. For us... We are sadly all slave os the money... A character, we are all our own character mate... At the end of the story if you can not feed your children, your wife or even yourself you'll die...
