From American and Western European English Speaking writers, this is true.
I have paid 5-10c per word for articles between 500-1000 words, that were all very well written in Eastern European countries by expats and fluent English speakers.
A few colloquialisms needed editing out, but if you are getting only 5 articles a week, you are spending $300-500, and 1-2 hours of editing per article if that (which includes formatting, adding hyperlinks, etc).
