Dear Yaakov and Michael,
You raised good points. There are comprehensive and reliable sources that address modern business issues from a Torah point of view. There is a wonderful website, http://www.darchenoam.org/ethics/business/bus_home.htm
, which lists many of the important books, classes, and essays that have been presented on these topics.
Specific business questions should be sent to on eof the authorities listed on the site, such as Rabbi Aaron Tendler, Professor Aaron Levin, and others, but it is important to first embark on a basic study of the sources, as is presented on the site.
