Is it "usually women" who do the unglamorous jobs that no one else wants to do? This doesn't really seem true, but maybe you have a source that shows it?

If referencing modern society in the west, who is fetching wood and water?!
Is this stat from 1870?
There's more to unpaid labour than fetching wood and water. Women still do significantly more housework than men, even if both hold full time employment.
However, citing a stat from before anyone was born, isn't helpful in a modern context.
Replying to this with "it is still true, because", now that your citation fell flat on its face, may not be the best strategy.
You’ll notice there’s a push to get women into comfy office jobs like programmer and not strenuous jobs like oil rig worker.
Someone can reply to me and cherry pick to show counter examples but for the most part it’s men doing these jobs.
