Because it's a waste of time

[Oeditpus Rex]

The only reason cursive writing methods were ever taught in schools was to make kids seem like part of the upper class. It's much more valuable to be able to letter (not "print" ) clearly.

As for signatures, you can use an 'X' as long as it's witnessed.

Look at it this way: How many protest signs, or signs of any kind, for that matter, have you seen in a cursive method? How many web pages? How many newspapers and magazines?
