Being expert-friendly is not a problem per se for a language. What matters is the ratio between sufficient wage and productivity increase as compared to other languages. By "sufficient wage" I mean paying your experts enough so that they become less rare.

I wouldn't mind paying someone 3 times as much if its expertise in the given language means he can be 10x more productive than an average programmer in an average context. (I personally have measured a 30x incrase in productivity by switching from ruby to clojure and have observed the same phenomenon with other people).
