In the old times,primary schoolstrained kids to have good hand writing. Later, the education system changed and no foreign school teach that anymore. If you have some old native friends, they supposed to have much better handwriting than the youth.
More and more people start to use pc, laptop etc. We write less than 10 years ago. If you look closely, nowadays children do not have as good handwriting as their parents' in china too.
There's a fashion value difference.
