The reason selling has died is because with the advent of consulting fees and under-the-table deals we no longer sell product, we buy business. Let the first company that doesn't do this throw the first stone. But remember what Donald Fagen once sang:
Can you hear the evil crowd, the lies and the laughter, I hear my inside, the mechanized hum of another world, where no sun is shining, no red lights flashing, here in this darkness, I know what I've done, I know at once who I am..... I'm a bookkeeper's son, I don't what to shoot no one, don't take me alive.
