...from the article in the initial post:

"Kaiser's Ravenswood plant created a middle class where there was none. When the United Steelworkers Union was voted in after the plant opened in 1957, the hourly wage jumped from $1.78 to $3.25.

Three decades later, the aluminum works was sold to a group that secretly included Marc Rich, an American commodities trader who was living in Switzerland to avoid charges of violating the U.S. trade ban with Iran."

Note: That is the same Marc Rich who, with his wife, hosted lavish parties for Bill Clinton.
