It's really quite remarkable to me, upon reflection, how so much of our workplace used to depend on aggressive personal salesmamship. I found that out last decade as my "career" (in the sense of the last movement of the Shostakovich Symphony #13) as an individual contributor in IT collapsed. and found so many interviews for jobs based on commissions and aggressive behavior (which had been OK for my father a half century ago -- but he sold to retailers, not to individual consumers). In the Internet age, this sort of thing seems no longer appropriate. There are more people like me who don't like to be approached (in public when walking or by telemarketers) so it is getting harder for sales people to make a living. A new kind of cultural divide, with moral overtones, is developing.
I think that instead of just "American Hustle" (with all its legal issues now), we need "American Huckster", produced and directed by Seth Rogen (and maybe James Franco), and released by Columbia Pictures (Sony) as a summer movie.
