亚洲欧洲和北非的人口密集，不仅限于埃及，尤其是亚洲的东部，南部地区。所以我认为，首先一个很好的做法，就是分析世界各地的人才分布，给他们按专业领域，主要住地，移动灵活性等分类。这个数据库不仅应该只涵盖个人，而应该涵盖不同行业的团队。例如，对中国的基础设施工程团队进行评估，看他们擅长什么，在什么建设条件下，他们的技术服务的质量等等，一旦有跟工作相关的人移民，雇主就知道去哪里找到合适的人，甚至在国际范围挑选。除了与工作有关外，还可能有人口社区相关。几十年前，由于中层和下层缺乏劳动力，美国开放了拉丁美洲的移民大门。结果它吸收了大量低质量的拉丁美洲人。这对美国经济造成了灾难性的破坏。因此，当任何一个国家大规模引入人口时，必须考虑到人口的质量和国家容纳人口的能力。来自中东的难民给所有国家带来了无法估量的难题.

The dense population of Asia, Europe, and North Africa is not limited to Egypt, especially eastern , southern regions of Asia. So I think , first of all it is a good practice to analyze talent people all over the world, give them classifications, professional fields, main residence, mobility flexibility, etc. This database should not only cover individuals but teams groups in different industries. For example, China's infrastructure engineering team can be rated to see what they are good at, under what construction conditions, the quality of their tech support, etc. Once there are job related people emigration, employers know where to find the right ones, even worldwide. Besides job related, there can also be population community related. Decades ago, Because of the lack of labor in the middle and lower levels, the United States opened up its immigration door to Latin America. and as a result it absorbed a large number of Latinos of low quality. This has done disastrous damage to the American economy. So when any country introduces population on a large scale, it must take into account the quality of the population and the capacity of the country to accommodate it. Refugees from the Middle East have brought incalculable problems to all countries.
