That’s the thing, we do teach kids to write well. In a script they’ll actually use. It almost feels like you feel the need to make this pointless argument just so that you can justify the time you wasted learning cursive. Like as a coping mechanism.
We just don’t have that problem. We write what we need to write in a way that works and for everything else we type. I feel for you that your students are evidently so destitute and your school system so inadequate that you don’t have basic, cheap technology available to your students and children, but that’s just not a problem we have. It’s not any kind of deficit for us that we don’t teach cursive anymore. It’s the most non-issue with our school systems anyone could possibly think up.
