Instead of comparing '20 smarty JQuery guys' with '200 average Java programmers', how about comparing '20 average JQuery programmers' with '20 average Java programmers'? Or comparing '20 smart JQuery guys' with '20 smart Java programmers'.
There are lots of jQuery programmers. They know (how to read the docs of) the whole API and close to nothing about low-level JS. jQuery is a powerful and useful tool but it has grown to "replace" JS in the minds of many.
Just to be clear: I don't like this situation at all.
