What are some of the changes Troy does not recognize in fences?

In August Wilson's play "Fences," Troy Maxson fails to recognize several changes in society and his personal life. He struggles to adapt to the evolving racial dynamics and opportunities for African Americans, clinging to his own past experiences of discrimination and frustration. Additionally, he is blind to the emotional needs and aspirations of his family, particularly his son Cory, who seeks to pursue a football career. This disconnect ultimately leads to strained relationships and a tragic sense of isolation.
