A recent review of pay scales indicates that CEO's now earn an average of 419 more pay than blue-collar workers, compared to a ratio of 42 times in 1980.

a.
b. that, on average, CEO's earn 419 time the pay of blue collar workers, a ratio that compares to 42 times
c. that, on average, CEO's earn 419 time the pay of blue collar workers, as compared to 42 times their pay, the ratio
d. CEO's who now earn on average 419 times more pay than blue-collar workers, as compared to 42 times their pay, the ratio
e. CEO's now earning an average of 419 times the pay of blue-collar workers, compared to the ratio of 42 times


is CEO's singular or plural? What's up with the pronoun? Puntuation... The comparison... ? I am so lost.
