My life was changed forever when I learned I could say that 6% of 50 was 300%.

I prefer to keep it technically correct yet evil and confusing. 6% being a fancy way to write 0.06 or 6 * 1/100 means we can take 6 * 50 * 1/100 and simplify to 300 * 1/100 and then represent that as 300%.

While that’s certainly true, I don’t think that doesn’t apply to women’s clothing as well nor does it change that women’s clothing not having pockets is kinda bullshit, even though you can technically add your own after the fact.
It would be more of a “yes, but…” Situation if women’s clothing that didn’t have pockets always fit perfectly and hit all the criteria you mentioned. They have that problem and they don’t get pockets.

While true, it’s hardly fair that I, as a man, don’t need to learn to sew, buy a sewing machine , spend time getting materials or actually doing the sewing in order to have good pockets. My pants just come with good pockets.

One of the defining characteristics of that eras literature, not just sci-fi, is a reflection of the cultural belief in a narrative history.
The belief that society will advance, and that there’s an inevitable direction that things will go even if there are setbacks.
