To a much greater extent than other language, the United States suffers from confusing spelling. A point that’s well-illustrated by this video:
And all this is to say nothing of the fact that the same word is often spelled differently (“colour” vs “color”) depending on which country you’re in. This all makes it more difficult for immigrants to English-speaking countries to become literate and, in general, it’s an extra disadvantage for children whose family background puts them at a relative disadvantage. And as English has increasingly become the international language, it’s particularly problematic for the world to be operating with one of the languages in which it’s hardest to communicate.
Obviously, you wouldn’t want to organize some kind of totalitarian effort to force everyone to adopt a new, more logical spelling system. But spelling conventions have changed over the years, and other languages are easier to spell in part because there’s more deliberate effort by leading institutions to play a custodial role and implement periodic reforms. Something similar for English could be very useful.
