Let me start from the end. When I was referring to sacrifices to bring costs down I was mentioning the fact that the Chinese owners of restaurants in Milan are willing to work 7 days a week and 16 hours a day and their families do the same. I also think that sometime they treat their Italian employees with much more respect then the Italian owners.
In relation to the American scenario I can speak only out of my experience. I have worked for the university system physics/engineering for 10 years and then I moved to the semiconductor industry for 18 more years. First the educational system is really targeted at teaching skills more than at educating people toward love for learning and developing a taste for knowledge. I can see that especially now that I am directly involved in looking for colleges for my son. Second it is a culture of entitlement, a lot of people feel that they are owned jobs and security just because they have skills and that is false and dangerous because people loose flexibility and adaptability. Third I noticed that a lot of people become comfortable and they are not willing to learn more everyday, I have seen a lot of intellectual inertia and that is very dangerous especially for senior employees with higher salaries. People confuse seniority with experience and capability, that is not always true.
I am not saying that American in general are not able to confront an immigration of highly capable incomers; however, the good ones want rewards that immigrants do not seek as necessary. A lot of high tech industries are now turning into commodity churners and thus the costs must be kept down, a few are willing to take a 10% pay cut and stick with the company a lot are ready to jump ship as soon as a better offer is out.
