Mark my words this will eventually affect their artistic output. Great art has always come from the personal experiences of artists and if your personal experience only consists of partying hard and throwing money everywhere you are not going touch someone's heart from your music.
This but that goes double for hip-hop artists. There's a lot of artists that brag about women, clothes, jewelery and their wealth. The best songs are made about their pain, dreams, real experiences, and that's reflected in the top albums of all time. Tupac's best material came after he was released from prison. His mother was imprisoned much of her pregnancy with him, as a member of the Black Panther Party. One of his family members has asylum in Cuba because of something she was involved with.
He made the best music when he wrote commentaries on life. His life, people he read about, prison, and activism. Is anyone going to remember Dynamite? What can they sing about? Gucci Gucci Gucci? Nas wrote a letter to an imprisoned friend that always stuck with me. He rapped about life changing while his friend was in prison.
