Billy Graham
Billy Graham is an evangelist of God who was called to minister to presidents across the globe. He founded the Billy Graham Evangelistic Association in 1950 and was a spiritual advisor to many Presidents. He had an estimated net worth of about $25 million and a private jet his congregation bought for him.
The wrong business is right. On the other hand, I do know the Billy Graham ministries were flying medicines and necessities all over the developing world, but they were doing in old Cessna 172s and such.
