This does not imply men are better than woman, this implies that men are better off than women.
This is apparently the intent of the first explanation of Rashi in Menachos 43b when the gemara says a slave is the same as a woman, Rashi says 'for she too is a servant to her husband like a save to his master'. Rashi's other explenation is the one cited in classic works of halacha starting with the Tur inn siman 46, but I would like to focus on this one.
Throughout history women have been subjugated and abused. This unfortunately seems to be ingrained in human nature. Whether you believe in a literal reading of the story in Eden or an allegorical one, at the end of the day the Torah was compelled to point out this unfortunate reality.
We in the modern world have learned to respect and appreciate women, but any step backwards proves the unfortunate reality, as seen in all backwards societies where the woman are subjected and abused.
It is in light of this unfortunate state that we thank Hashem for not putting us in that position. But we should remember that we can overcome all the curses of Eden. We can easy without sweating, we can raise children happily, and we can have equal partnerships with our spouses.
