How come the parent post is rated as informative/interesting? It has NOTHING to do with the point of TFA but to arouse those who are anti H1B. Of course, TFA highlighted only high number. If you really dig into the data given as a link by TFA, you should at least see what TFA is directed to.
TFA gave a link -- http://www.flcdatacenter.com/d... -- to FLC site which is the list of prevailing wage for all job codes related to areas in the US. The only missing link for comparison in TFA, for me, is the hiring salary from all companies. As a result, it looks to me that TFA assumes/uses those high salaries as a standard paid by most companies (look at the number of applicants given in TFA example) which is unlikely true.
I understand that FLC listed the minimum salary based on job title that a company must pay (if you download and look in the readme.txt). The only problem is that it is just data in the book, but not the data in practice. Think of it as book keeping in accounting, a business owner may keep 2 books - one for submitting taxes and the other for real revenues/losses. Thus, the real salary may not reflect the one used in the application, and it is usually lower for those companies that know the work around.
