the best strategy you can use to clarify the concept of scanty remuneration is to use context clues within the sentence itself.

the sentence states that includes the term "scanty remuneration" provides you with the clues that "he has monopolized all the profitable employments" and "from those she is permitted to follow, she receives but scanty remuneration". according to the context, she is only permitted to follow some profitable employments. the use of the word "but" before "scanty remuneration" provides you with the meaning of something that has a negative connotation. thus, she has very little access to a proper remuneration.
