When people are in money the feel that they are superior and more powerful . the greed of money makes a man arrogant. and for that false power of money people leave behind family , friends and even loved ones.
Money changes the character of the people, as after becoming rich, many people think that, they are the powerful, they are the rich person in the world, and forgot about the relations, etc...
Thus, the money changes the character of the people.
There are many people, who are the best examples for this.

Thank you.
Hope this will help you.
