Should Indian product companies are still using traditional marketing system or modern marketing system?

Today in 21st century where most of the Indians companies and leading marketers still believe that traditional marketing is still good and effective because marketers have the power but in modern marketing users have the power. another difference is that in traditional marketing marketers focus in branding but in modern marketing marketers have to think about passionate users and lot many difference are there according to marketing experts but my viewpoint and study says that traditional marketing gives huge profit margin then modern marketing. Modern marketing are not much effective because its costly for the consumers still. Lets say example  a common men/women wants to purchase 1 kg salt. So many brands are available there in the market. he went nearby on small shop and ask I want 1 kg salt. shopkeeper give him 1 kg salt of one particular brand. he ask i want another brand then shopkeeper told him this one is good and better then what you asked. Customer think ok whats the difference salt is salt whatever brand may be and he purchase. why because salt is low end product but in the case of high end product say laptop, mobile or you want to purchase a flat or house hear customer gather knowledge which one is better because hear investment is more. Its only dilemma...reality is that the knowledge given to the customer is given by the marketer. another very good example to prove my point is that during recession or economic slowdown builders selling their flat at 15 lacks to 20 lacks and they are making huge profit but if recession is not comes in to the picture they sell the same at 40 lacks to 60 lacks. name is different product is different but product reaches to the customer in the same way only traditional whether you purchase laptop, flat or salt...traditionally....
