I think some people are mixing up accent with phonetics abd with spelling.
All languages have different accents /dialects, English is not a special case, and they still manage logical spelling.
Many of those languages went through a spelling reform to simplify things and improve communication.
English had an opportunity when a dictionary was compiled (I forget which), but it was squandered by making frequency the deciding factor to pick a spelling. Et voilà , inconsistency continues.
