In summary, stainless steel does not rust because it is sufficiently reactive to protect itself from further attack by forming a passive corrosion product layer. (Other important metals such as titanium and aluminum also rely on passive film formation for their corrosion resistance.)
White Collar. White-collar workers usually perform job duties in an office setting. They are highly skilled and formally trained professionals. Many white-collar workers, such as accountants, bankers, attorneys and real estate agents, provide professional services to clients.
In the United States as a whole, there are almost as many immigrants in white-collar jobs (46 percent) as in all other occupations combined. In some states, more than half are in white-collar jobs. However, not all white-collar jobs pay well, and the share of U.S.-born workers in white-collar jobs is even higher.
