Misc. CofL49, p14 "Endless, convoluted incest"

[Mark Kohut]

have you been a little puzzled by that brilliant metaphor--incest with another's future life--- that the narrator
uses to describe Mucho's feelings about all the people--each shadow--- who, with that moving list of car detritus, trade in their cars for "a futureless automotive projection of somebody else's life." ?"As if it were the most natural thing. To Mucho it was horrible. Endless, convoluted incest."?

Well, I always have, thinking it is an example of TRPs over-the-top extreme metaphor-making of genius. 
I still believe that and I have just learned this:

 "transference was another concept contested and defined in various ways by
the early psychoanalytic moevement"..

Jung: It was true that transference was mainly projection...'but projection was not (always) true of kinship libido'.
Therefore transference satisfied the primitive need for quasi-kinship connections."----

"Jung believed that because exogamy has triumphed [in human society] over endogamy we were all as a consequence
atomized individuals and strangers....[Jung] then cited the work of anthropologists who regarded endogamy or the incest tendency
as a genuine instinct which, if denied realization in the flesh, would realize itself in the spirit."...p. 428
