Can I Buy A Vowel

The factory where syllables are molded into words
ran into unexpected issues, and,
as consonants and vowels diverged, their separated herds
were getting quite hard to understand.
When asked, the cunning linguists said: "supply chain is at fault.
We need to bring our syllables back home.
'Cause otherwise, our language risks recession and default
We can't outsource our verbiage to Rome!"
Yet others said: "Let's tax those vowels! They're far too free today.
We can't just have a syllable at will."
That effort beaten back, with vows that "liberty must stay!
I say wow-wee, you say wow-wee, just chill."
Well, in the end, the syllabi adjusted to supply,
and if your consonants need stretch, a vowel you must buy.
