Poor Susie must be royally pissed off with people asking her how she got involved in psychoanalysis. She's a very intelligent and articulate woman, so it must be doubly frustrating for her.
Freud's ideas doesn't have any market value! Because he had stated the rationalisation as a defence mechanism and he is refusing the rationalisation. On the other hand; all the financial systems and world economy is based upon rationalisation. If you look at the any book of finance or economy, it starts by addressing the notion of rationality. If you want to make money choose Rene Descartes instead of Sigmund Freud. Freud wrong! Descartes right!
