I would support the contention that this is not a native English speaker. True, I have met (and unfortunately worked under) some pretty atrocious spellers born and bred in US of A, but the pattern here does not fit. Native speaker's assault and battery on the language may be of this severity, but it will be in a different style.
In fact, this reminds me of an essay written by a classmate I have read during the brief time I spent in college. His grammar, syntax and spelling were very close to this. The subject was even better. He had this theory that famous men with moustaches were generally evil, like Hitler and Stalin. Famous men with beards were good. For some reason he thought Einstein had a beard, even though he mentioned he had a poster of him on the wall. How that guy ever made it into English 101 is beyond me. He was Chinese.
I would attribute things like this to just-off-the-boat confusion. I also have a feeling that a well-meaning hippie teacher had a hand in creating the tossed salad between the kid's ears. I bet given 15 minutes I could make him see the light.
