Natal charts and the natural laws of the universe in general are the cause of this. Everyone is born with a different soul and the vibration that makes up their soul determines the quality of the life they have. The universe, nature and life are all unfair and can be brutal at time. Even if a 'good' person has a kind heart and constantly helps others around him, if he was born with an unfortunate natal chart which causes his soul to attract constant misfortune to him, he will always suffer regardless of how much of a good and respectable person he seems to be. That's just how life is on our world.
Average people who don't have knowledge in the occult will always be at the mercy of, and oblivious to planetary and universal forces as well as at the mercy of other souls that are stronger and also who may have occult knowledge to manipulate them. That's just the harsh reality of life.
Yes some people can just be lucky and be born with a positive natal chart that can bring them endless happiness and bliss in life and the reverse can be said for other people who are just unlucky and get shit on by life.
Many gentiles suffer because of the centuries of endless Yehuborim curses that weakens their souls as well as Yehuborim doing rituals that sends their 'Sins' to gentiles. These 'Sins' being things like Poverty, suffering and Misfortune. It's just an act of Yehuborim witchcraft done by Yehuborim to pass any and all of their suffering onto gentiles while they themselves can have all the knowledge, wealth, and power to themselves, along with any happiness in life.
This is why so many A-list celebrities and wealthy people are Yehuborim themselves. They just weren't born with these negative afflictions attached to their souls due to themselves being Yehuborim. And because they have spent centuries cursing and trying to pass all of their suffering and woes onto gentiles.
This is why normal people struggle and suffer so much in life.
