Giles seems to be operating on the assumption that you can't charge a reasonable amount for PHP work. Does this imply that he views himself as a commodity programmer? That if he were to be doing PHP work he'd be doing it at the same caliber of an outsourced shop in India?
Of course if this Giles character knew anything about economics he would also know that complementary products have complementary demand curves. So, the more PHP applications out there means there's more demand for PHP programmers.
