What does the autor mean when she says in paragraph 5, "I'm lucky my father believed daughters were meant for husbands. It meant it didn't matter if I majored in something silly like English

To Me, It kind of sounds like Sarcasm, Maybe the daughter wanted to go o college to major in English but her father didn't think she needed to as long as she had a rich husband and did all the chores like cooking, cleaning, etc.
