Well said.
I am currently as a area ops mgr in Asia for a US carrier (on contract). I would probably not have gotten the job without the license as the carrier flies under N reg and that way we have to comply with local CAA regulations of every single country, as well as with FAR's and ICAO regs.
I think it was mentioned already in this thread, that the US is one of the only countries in the world where the license is a legal requirement, while many other countries have similar trainings (Germany, England, Canada, Australia), which are based on recommendations (welcome to ICAO, half of the chapters are recommendations in order to cater airlines globally
).
It is getting harder and harder to penetrate the HR systems of mega carriers. Better chances are within the exploding business jet segment.
