You have hit the nail on the head. The reason that Silicon Valley has so many of the Chinese/Indian/Other nationalities is simply because of the volume of available "Good Enough" Engineering talent. In most of these cultures a Master's degree is almost the norm. With this in hand, the practical aspects can often be learnt in training/on-the-job. Given that much of Modern Engineering has been systematically streamlined and commoditized, you really don't need very much "Creative" and "Out-of-the-Box" thinking as much as people who can manage and contribute within the existing framework and systems.
