Thats how the world goes right now.
Agree. Rich becomes richer, poor becomes poorer.
So who's to blame? The rich or the poor?
Wealth is relative.
You are not rich of poor. You are poor compared to someone and rich compared to someone else.
Getting poor make the others richer. Getting rich make the others poorer.
To have everyone on the same level, you must force everyone to be very poor and take everything just for you, this is called Communism.
