Ironically, based on the original comment, the issue is that East Asian countries (like Germany, which was the archetype industrialisation model for East Asia) are largely run economically for the benefit of large corporations. So developers are hired en masse like every other employee (in particular, skilled labour is hired once after graduation), there is a stigma against switching jobs (even if you could find somewhere to move), employees are essentially interchangeable, and there is almost no innovation.
The original comment is hard to understand. Germany and Japan are two of the absolute worst places on earth to be a consumer/worker in the developed world (the IMF even produced a paper on this in an attempt to put pressure on Germany to improve standards for workers). The US is nowhere close to having a management aristocracy because the system is open. Even in the UK, which has a similar economic model, the low-level of competence among managers is actually a major factor behind weak productivity growth. People just long for systems that aren't like the one they have, low levels of employee turnover are not a panacea, they led to heavily rigid management and are often linked to a high proportion of unproductive, family-owned business that are managed by birthright...professional management is, innately, open. If you look at Denmark, high levels of employee turnover actually lead to higher wages because it creates so much more innovation (most countries that have any other model, including Japan, are trying desperately to get away from it).
Afaik, France is the only country that has the aristocracy model: it is usually literally impossible to be promoted into management if you didn't go to grandes ecoles, and most of the top jobs in govt and business are just rotated through this group of people. Unlike the US, the curriculum of related courses often has no relation to reality, and is designed to be as complex/abtruse as possible so entry to the higher reaches of society can be limited. It is difficult to understate how envied the US system of management is compared to this...it isn't just that the US does this slightly better, it is that the US is at 100, and everyone else is at 10. It isn't close.
