The larger the prison the easier the control. The larger and more comfortable a prison is inversely proportional to our
ego's ability to accept it as such. Bigger house and more money wealth means there is less chance of accepting the problems of the prison, therefore the problems must be internal. This leads to an easier stance for addiction and a self-fulfilling prophecy of negative self-worth.
A junkie from the hood that had a horrible upbringing is a junkie because he is in a prison and sees no way out.
I think the rat experiment does translate. For the rats, the larger environment satisfied their simpler liberty and
freedom needs so as to not be in a prison any more.
For humans, the liberty and freedom are not directly connected to a big house and money wealth, regardless of how much the politicians, corporations and banks market it as such.
