What would be some examples of "environmental estrogen-like substances associated with affluence?"

BPA: http://en.wikipedia.org/wiki/Bisphenol_A

Bisphenol A is in a lot of plastics (See: Polycarbonate), including soda drinks, and leeches into the drinks themselves in small amounts. BPA exhibits "Estrogenicity", in that it mimics the behavior of Estrogen in the body. Nearly everyone in developed countries has some level of BPA in them.

BPA has been linked to Obesity as well: http://en.wikipedia.org/wiki/Bisphenol_A#Obesity

Note that the BPA associated with soda is present in metal containers, as part of the plastic liner used to protect the can from the acidic soda. Those liners are in lots of other metal food containers.

Disposable plastic beverage bottles are almost all PETE, which doesn't contain BPA.

Quite a lot of plastics leach chemicals that can have estrogenic activity, according to this study http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3222987/ Take it with a grain of salt though.
