The writer of TFA clearly specializes in writing. He/she probably has a good academic prose style, and good research skills, along with a jstor subscription or nearby university library. Quite possibly, he did a liberal arts or social science degree, which gave him the necessary practice; but found the job market unexciting with those credentials.
Go back and read TFA. I'm saying this not to be an asshole but because it's genuinely fascinating.
The author states that:
* He went to college to be a writer and found out that there's more than one way to get paid for what you write.
* He uses mainly Wikipedia (for background), Amazon for the free pages, and Google Academics for the abstracts. Everything else he spins from educated guesswork and outright bullshit with lots and lots of filler.
* He doesn't edit his work at all, this helps him work faster and heads off requests for him to "dumb it down".
* His clients often thank him for making typos (presumably because it looks more authentic that way).
He's not producing high quality work for top honors, he's producing "good enough" work for the sake of graduating at all. It may pay to get A's but C's get degrees, etc.
I've said for years that not everybody needs a college degree. I would guess (I would hope) that this guy is helping along the raft of mediocre graduates who won't ever really use their degree except as resume fodder. Unfortunately this just devalues college degrees even more so that employers keep on requiring degrees for jobs that don't really need special training.
He's right about one thing, blame the colleges that are more interested in collecting tuition fees than in producing actual, competent scholars.
