A trader/businessperson is supposed to have product(subject) knowledge(complexity) for customer/s(consumer/s). PRODUCT KNOWLEDGE IS "FOR STATE" of product existence. Product knowledge is not "being state" of product existence. Product knowledge says that product/service doesn't exist by itself naturally. Trader(businessperson) has to maintain product/service characteristics(qualities) for better consumption towards personal-mind satisfaction and pleasure. As long as human wants are not fulfilled by products/services from other's mindset,so long do "that" human body wants exist to prevail as bad(evil) later. So businessperson duty is to business solution of public issues but not leadership duty to be issue to public issue. However business appears as leadership unless and until people's mind matures. That means both "reverse to reverse" and "reverse" need be inculcated by everybody for want of human dignity,name(word)-prevailance and pleasure-satisfaction. Or else you will be made so by other/s.
