Good and bad in the sense that they can achieve management's directives? Yes, anyone from any culture so long as they have a practical grasp of the language they're working in can adapt to the circumstance.

But the culture starts at the top. Everything within the U.S. spiritual ecosystem is geared towards a superficial approach to all things. One example in the vein of engineering is Ford vs. Toyota. Anyone who has owned both of these can attest to the difference. There is a craftsmanship culture within Japan that I'm sure we're all acquainted with, but there are also much more subtle values at play (f.e. duty, sacrifice, etc.) that color everything an individual, and the society he makes up, touches. The individuals of America do not have strong values or sensibilities. I want to say this is because of its quality of being a "cultural melting pot." But this aspect of it doesn't turn it into a stone soup, where all the different and varied ingredients work together to make something unique, with surprisingly complimentary flavors. Instead, I think it turns into an actual crucible, where people of all different mettle are melted down; and all of the extraneous spiritual slag is scooped off the top, before being poured out as a completely uniform metal, without a noticeable difference batch-to-batch.

Instead of refining and building upon a culture, as 99% of other nations do, America specializes in annihilating it, and integrating the stray quality here and there that it finds useful towards its ends. And its ends is something I cannot even begin to know.
