There is more simple way to tell, and I don't know why other players or people of forum or the developers don't reply on this thread.
Is very simple, a child saying to him parents, mom can you give me a gift card to buy some things on this game that I like?
Parents says : why you need the money? Work hard to get what you want!
Child :I want to buy some stuff to not feel a zero!
Parents says : give you money? Give you money to not feel a zero?
How much money you may need to feel little equity?
Children says I DONT KNOW !
Parents says, delete this game now and never play, I don't raise my children to feel zero on game!M
Deleted and I'll buy you a PlayStation and a lot of games to play enjoy and be HAPPY!!!
