It doesn't. English does not get along just fine.

Say 'cucumber'. The sound of the first syllable is very different from the second, even though both are written the same.

Say 'stake' and 'steak'. Different graphs for the same phonemes.

Say 'E as in elephant'. Two different sounds for 'e'.

etc.

Present day English is so bad that written language is divorced from spoken language, but it is not bad enough to unite all speakers behind a spelling reform.
