Money is not everything in life but people run after this money. It is only for this money that various unpleasant events occur. Greed for money is terrible. From low class people to high class people all run after this money. Kidnapping, murder, embezzlement are all done by people to increase their money. Conflicts arise between people because of money.
All the sins you mentioned are not caused by money, the root of everything is human greed, selfishness, absolutely not money's fault. Money is just a product that we create to serve us, but we also make it into something we have to run after and obey, but in the end, the manipulator behind everything is our greed.
The disparity between the rich and the poor is created because of this money. You have rightly said that when people have money, people's ego increases. The addiction to money income makes us forget that we are human beings and we all have to leave this world one day by giving up the illusion of money. If you think about these things, you will not think that money is everything in life. When you leave the world, people will say what you have done for people. If you have done something good, people will remember it for the rest of their life.
I believe everyone, including you and I are aware of this. But we can't do that because no money in this day and age affects not only you but also the lives of your loved ones. So you can't stop making money and always treat it as everything because when you have money, you will have it all.
