enthusiasm for socialist reform.
B.  during World War II, wage and price controls forced employers to use nonwage forms of
compensation to attract workers.
C.  poor health conditions at the beginning of the 20 th century prompted the U.S. government
to require new companies to offer health insurance to employees.
D.  the American Medical Association successfully lobbied the U.S. government to provide
subsidies to companies offering private health insurance to employees.
