no more financially secure than do people working in blue-collar industries.
(A) no more financially secure than do people working
(B) not any more financially secure than do people working
(C) not any more financially secure than do people who work
(D) no more financially secure than are people who are working

(A) no more financially secure than do people working
Correct. Grammatically and logically correct
(B) not any more financially secure than do people working
Incorrect. This is grammatically correct but wordy than A
(C) not any more financially secure than do people who work
Incorrect. This is wordier than B - "people who work" < "people working"
(D) no more financially secure than are people who are working
Incorrect. Its too word-y and use of are is twice which feels redundant.
(E) not as financially secure as are people who work
Incorrect. Changes the meaning from the original sentence
