This figure has been traditionally used by Calvinists who also believe in predestination.
Some bright spark concluded that although we don’t know who will be saved, there is a simple way to have a pretty good idea.; God will obviously only lavish his largess on the saved. IE the rich and prosperous. Again obviously, god will not be generous to the damned. IE the poor, of whom there are many, many more than the rich.
The Calvinist idea of the deserving rich and undeserving poor has been a powerful idea in many societies, including our own. The concept of the undeserving poor still permeates countries such as Australia, the UK and the US. It is often reflected in government welfare policies.
If you haven’t read it, I recommend ''The Protestant Ethic And The Spirit Of Capitalism" by Max Weber. An oldie but a goodie.
