The relevant question is -- does it make sense to teach our children to print, wait until they have mastered it, and then RE-teach them how to write (using a totally different script -- that is, cursive), then wait until cursive has been mastered and then tell them we don't care what they use (
hence encouraging most of them to go back to printing).
(The bold is mine.)
That's where you lose me. Why on earth would that encourage them to go back to printing??
Well, I'm not making it up

. It does seem to be the general consensus that they don't really care what kids use in the later grades. Most kids who don't have exemplary cursive are encouraged to print because it's easier to read. Of course, after schooling is completed, there is no context (other than something like wedding invitations, maybe

) where it is required or even allowed! Imagine turning in college papers or filling out forms in cursive -- not a great idea!
My 8 year old is THRILLED to be learning cursive. Her 10 year old brother's script is far more legible than his printing.
I agree that kids who might enjoy learning it should do it, as a kind of practical art or hobby. Not as part of the public school curriculum. I want my kids' teachers to be teaching math and reading and literature and science!
And when did our kids suddenly become too stupid to handle cursive? I'm never in favor of the "dumbing down of America."
I'm sorry, but this made me

. The point (or at least my point) in abandoning cursive is that it is NOT an intellectual endeavor that we need to waste time on in schools. It can be fun; it can be pretty; it can be a nice hobby; but it is not a scholarly endeavor! In fact, I might argue that our kids are too smart to waste their time on cursive, unless they choose to as an extracurricular activity.
If we're going for strict Utilitarianism, then why teach Algebra, since not all will need it. (Note: I'm a math teacher.) Why teach literature at all? Why teach geography when so many kid have access to a GPS?? Why teach spelling when there's Spell check, or Grammar when there's grammarcheck? In fact, why teach writing at all? Why not just teach keyboarding???
Why teach anything beyond how much salt to put on the fries???
I think that most "useless" subjects we teach kids in the higher grades are directly related to college preparedness. A lot of kids might find algebra useless if they don't go on to college or do a strictly non-science college program (although they will usually have kids do some math as a breadth requirement, anyway). But we teach them algebra so they can be computer programmers and engineers and architects. I'm surprised you've never pondered this concept, being a math teacher and all. Sure, some won't use it, but we provide it because a good proportion will in some capacity. Cursive handwriting? Again, other than wedding invites and hobby purposes, I doubt that any child will need or significantly benefit from cursive handwriting later in life.
The point is -- cursive handwriting is wonderful as a hobby and any child who wants to learn it should be encouraged. There could even be electives or after school arts programs devoted to it. But in school, where they have precious little time to learn academic basics? I think it is a waste of time.
