$45/hr salaries at first seems pretty high except it probably corresponds to loaded average salaries (with benefits factored in and they are usually about 25%-30% of the total). In addition, alot of the process will be automated so that the workforce will probably be top-heavy with engineers, chemists, and managers. Hence, the $45 number is not that high.
Assuming 25% in benefits, this works out to an average annual salary of $57K which is reasonable for a workforce that includes alot of professionals and managers.
Of course, maybe Menka really thinks they'll pay $45/hr for someone working a forklift... who knows for sure.
