-> They won't learn how to tie a tie properly.
-> Its a draconian measure that attempts to make kids 'look smarter' without actually teaching them the value of making themselves look 'smart' of their own volition.

-> Uniforms, especially ones with ties involved, are ridiculous byproducts of an age where education was based on industrialism.
