I really like the sentiment of this, even though it's obvious that there's a not-so-underlying theme of traditional gender roles.
That's the whole point of the poem - to illustrate clearly how absurd gender based biases are - and have been since "Man" crawled out of caves. This should have been made evident by Rosie the riveter and again when it became evident a single income was not enough to support a family in most homes today.
I joined the military in 1971 and became an electronics technician maintaining radio systems for Air Force air traffic control facilities. That was a "man's world" within a man's world. Yet as is often the case, the military was at the forefront of equal opportunities for all. While the numbers were few, we had females in our ranks and they got equal pay for equal work. And for sure, some of my best bosses have been females. Yet when it come to reaching the top levels in military executive positions, there is still a glass ceiling.
It took until 2008 to promote the first female to the 4-star rank in the history of the entire US Military. The Navy did not get it's first female 4-star admiral until 2014!
Now of course, there are much fewer women in the US military, less than 15% of the total force. But just 7.1% of the top ranks are women. Not good, but still MUCH BETTER than in the civilian world.
I was a single parent for quite a few years so I perhaps have a different perspective. I know what it is like to make a home and to support a home for my family. It ain't easy.
