Why is it so?

Why is one man down at the mouth and another chipper? Why is one man joyous and prosperous and another man not up to scratch and schlocky? Why is one man fearful and anxious and another full of faith and confidence? Why does one man have a beautiful, luxurious home while another man lives out a meager existence in a slum? Why is one man a great success and another an abject failure? Why is one speaker outstanding and immensely popular and another mediocre and unpopular? Why is one man a genius in his work or profession while the other man toils and moils all his life without doing or accomplishing anything worthwhile? Why is one man healed of a so-called incurable disease and another isn’t? Why is it so many good, kind religious people suffer the tortures of the damned in their mind and body? Why is it many immoral and irreligious people success and prosper and enjoy radiant health? I just wanted to know all whys and wherefores. Do you dig what I mean?
