To quote that first link,
"The results of Study 1 indicate that there are significant differences in judgements of women’s attractiveness based on breast size as a function of men’s relative socioeconomic status. More specifically, the present results indicate that men in relatively low socioeconomic sites rate larger breast sizes as more physically attractive than do their counterparts in moderate socioeconomic sites, who in turn rate a larger breast size as more attractive than individuals in a high socioeconomic site. In broad terms, these results are consistent with previous studies showing that there is an inverse relationship between socioeconomic status and breast [33] and body size [41]–[47] judgements."
Note the inverse is not true - higher status does not correlate with preference for smaller breasts; rather it correlates with a lack of preference one way or another. The 'all breasts are good breasts' option.
