Unfortunately you have been misinformed. I'm sure your sources - your cousin and others - mean well and feel like they are sharing facts. Perhaps they are young and born into the religion.
I come from a family that is four generations deep as Jehovah's Witnesses.
This religion does not create people with wealth. This religion does not encourage self improvement or a positive outlook on life. This religion demands complete devotion and personal commitment from each individual. This religion preaches love and compassion on the surface. The deeper message is destruction, judgement and condemnation.
In reality the life of a Jehovah's Witnesses is filled with conformity, fear, depression, guilt, unworthiness, minimal education & minimal financial security. It encourages self-righteousness, arrogance, judgementalism, control and intolerance.
That is the bitter 'Truth'.
