He is suffering from what I suspected - a decaying mind. Brought about by early retirement. Once you disengaged from active work especially at young age, your mind and alertness starts to decline.

His repeated (copy and paste) posts are a manifestation of that. It is very hard for him to generate original thoughts.

He is also very hypocritical. He claimed that he had made his fortune, then in the same sentence, he start singing the tune that people working hard to build up their fortune were materialistic. Shameless hypocrite.
