I can somewhat agree with you, but it's not the the whole true. Marketing is not only about how to sell everything,to promote, no matter what, no matter how, just how to earn. No, to say it very simple marketing=profit+satisfaction of the customer. A person who has bought a product should be satisfied with it, if it turns out a product doesn't fulfill person's requirments, she/he won't buy it again, won't come for more. If something is well marketed of course it may sell better, but in case if the product is bad/not good quality - it may sell good, but only in the beginning. Then, for the longer period the customers won't buy it as before.
