Satanism doesn't condone being a freeloader
This is it in a nutshell.
Like it or not, most western societies take out taxes to pay for disability, social security, etc. If you have legitimately worked and find yourself unable to work, then that's what the taxes were paid for. If you are exploiting the system by being a freeloader, you're a thief. Simple as that.
You are also not responsible for the actions of your family. If your sons are freeloaders, this does not necessarily reflect on you. Sometimes the apple falls far from the tree indeed.
"The devil I'll bring you," answered Hagen. "I have enough to carry with my shield and breastplate; my helm is bright, the sword is in my hand, therefore I bring you naught."
