Mr. Trump has angered Mexico by declaring that the country was sending rapists across the border.

特朗普宣称墨西哥将强奸犯运到美国来，这就激怒了墨西哥。

For the sending countries, it reduces domestic pressure to pursue needed political and economic reform, and drains them of the human capital necessary to motivate and implement those reforms.

对于迁出国来说，这减少了国内的政治经济改革压力，造成了国家的人力资本流失。
