-What is the dual-wage system described by Benton-Cohen?

A) the practice of paying workers a very low official wage that is taxed at a low rate and another wage "under the table" that is not taxed at all
B) the widespread practice of paying Mexican Americans less than white workers for the same work or the exclusion of Mexican Americans from higher-paying jobs
C) wages for doing work in the mines: if the work is dangerous, workers get a second wage based on the level of danger involved
D) another name for wages and benefits, the latter being a "wage" that pays for insurance and pensions which workers don't see until they are injured, sick, or retire
