I would counterargue that corners are often cut just as terribly in the US. The corners are simply cut slower, because everything here is done slower.

For example, electronics built in the US are typically shittier than electronics built in China, despite taking significantly longer to build and employees being paid orders of magnitude more (as noted by companies like Apple, Purism, etc.)

Within our culture in the US there is a clear and comically obvious problem of bureaucracy and red-tape. This doesn't really exist in software yet, but the day our government gets its claws into the software industry is the day that innovation in the US can be put to rest. (Well, it's already happening - if you try to create a software startup that processes user data, you are probably breaking tens of laws you don't even know exist.)

There is also a cultural difference. One thing I have noticed when working with my Chinese coworkers is that they do not bullshit nearly as much as my other coworkers. They get straight to the point, deal in metrics and facts, and don't try to inflate their accomplishments. Maybe that's just my current work environment, maybe it's a cultural thing - I suspect the latter.
