Moids that are against women getting an education is how your society gets a massive downgrade. If we took it to its logical conclusions, a society where a bunch of women couldn’t read or write, in a society heavily dependent on those things, basic tasks wouldn’t be able to get done. Most societies now need literacy rates to be high, as without it, you couldn’t: make purchases online, drive, order food at restaurants, read nutrition labels, read the news, etc. Decreasing literacy rates in the name of marrying off women early and getting them pregnant would mean your society would have to go back to more primitive ways of living where you didn’t need high literacy rates, as otherwise, women with low education couldn’t function well on their own tending to basic household needs.
