I would assume that he would have accepted the earnings. As Whitey Basson has not stolen from anyone, neither has he broken any rules. He did build the company into one of the most successful ventures of today. He invested his own time and intelligence into growing this company. The income that they earn now is based on the hard work of Whitey Basson, thus this would have passed Kant’s theory.and also i think that this earnings would be seen as an imperfect duty because this depends on the preference of human. whitey basson cultivated his own talent by investing his good education and remarkable people skills into building the business and making it the most successful on today .kant would therefore accept the earnings for whitey has not stolen from anyone or broken any rules
