The passage starts out generalizing a concern that education does not actually teach but it ends up being about comfort in mediocrity.
Explanation:
The passage's theme is resistance to change.
The first line seems acceptable in a way, that there is skepticism regarding how much a school education could help a person.
Later on however it is quite evident that the passage is more concerned with the domestication of women as the farm secludes them to the domestic even as it presents a facade of the outside world.
Then the passage says that its not good to make sacrifices for the family and ultimately that people with an advantage are not interesting. It shows that the passage is fundamentally about resistance to change. A person with an advantage will take one out of the comfort zone hence is one that one should be afraid of.
