Humanity has been in something of a battle for thousands of years. Many with a religious (Christian) context call it “the battle between good and evil”. Attributing angels and demons to it, kind of making it fantastical and unreal. As something that transpires beyond our realm and thus out of our control. Nothing more than the inherent polarities, whos mere interaction births existence into being.
Simply said, this “battle” is merely the tension between “Service to Self” and “Service to Other”. This is the “battle” that goes on within the world structure and is even waged within ourselves. I believe most, if not all, higher teachings point to this conflict of polarity within ourselves, that becomes manifest unto the world.

The Polarities: Service to Others
Anyway.
He doesn’t go and look for his own place, due to his thinking that he doesn’t make enough money (even though he doesn’t take into account the money spent on his addictions). Nor does he make any friends due to his isolation.
To let him mooch off of you and allow this to keep going?
Kick him out of your house and have him learn for himself?
Service to Self
There is no “Good” nor “Bad”, only the interactions of Polarities
This is always a sign of control. If the very act of questioning is meet with hostility, then it is a good chance that its intention is to control a specific narrative. So, the point being, is that for those that see, we as a society may have an over abundance of a particular polarity.
An imbalance, if you will.
Not only is there an imbalance, but our social structure appears to have been built upon this polarity as well, further emphasizing and mentally coercing or corralling the minds of the people into this specific paradigm.
This is a main reasoning behind the observation of “programs’ running our thoughts, or the idea of being “programed”. This idea that many of us have programed understandings about ourselves and life as a whole, essentially indoctrinated into this mentality through our religions, education, media and generations of proceeding thoughts or beliefs passed on to us from family.
All this being said, there is still hope. These things have their uses, all things within Universe has their purpose, or they would not exist. Humanity is “waking up” to this misaligned view of life. It is only through challenge that one becomes stronger. Sometimes it is only through going through hardships and deceit, that a people may come to discover the power within themselves and rise above oppressors and deceivers. Sometimes, we have to reach a breaking point before we unleash our frustrations.
Things can only remain unbalanced for so long before they come crashing down, thus finding a new balance.
But that is a post for another time and, of course, a big part of this restructuring/rebalancing has to do with blockchain technology.
