Original sentence has comparison error. Comparison should be between white collar industries' people and blue collar industries people.
(A) no more financially secure than do people working: Incorrect, comparison error.
(B) not any more financially secure than do people working': Incorrect, not any more does not convey intended comparison.
(C) not any more financially secure than do people who work: Incorrect, same error as B.
(D) no more financially secure than are people who are working: Incorrect, the phrase "are people who are working" is wordy. The correct phrase is "people who work."
