I learned cursive in the US. Granted, this was in the 90s (which was only a little while ago, but for some reason people make it out to be ages ago).
Let's admit something here. Apart from the select few who still write, who in the US actually needs cursive? I'm not saying "down with cursives" - not by long shot - but would this Miss Jeantel (who really should have admitted 'I can't read cursive', not 'I don't') ever need to correspond in a situation where one will be judged their level of education and intellect by the handwriting a document?
I wouldn't recommend cursive taught in schools for the necessary purpose of using it. But rather for the fact that it stimulates the brain in ways that no other way of writing does, and it does so the same way that print handwriting does, but far more powerful. Here's a link to a rather "mainstream" site that dumbs things down a bit. But since their sources check out, I'll link it here since it's easy to read.
Basically, they're discovering that learning cursive increases the brain's maximum efficiency. It helps with fine motor control. It helps with many areas of cognitive development. And then there's the writing by hand itself. Unlike keyboarding, people who write things out by hand tend to write (on average) "more words, faster, and expressed more ideas when writing essays by hand versus with a keyboard".
Whether it's necessary or not for USAGE isn't a concept that I would use to leverage the reason why I feel we need cursive. I would rather everyone learn cursive because it helps the brain development so much. There are many things that we can do that are, in of themselves, entirely useless; but the spillover benefits greatly outweigh the time cost to learning/doing them.
I don't know, I think I would be fine with schools mandating cursive for a couple hours a week if it meant that, statistically, my kid was going to be smarter because of it. We have a hard enough time as it is passing standardized tests. If kids become more efficient, and smarter and express more ideas? Why wouldn't you want it?
I feel it's the equivalent of refusing a credit card with $500 on it free, because you can't use it the same way you can use cash.
