Why is the Philippines the country that produces the most domestic workers?

The Philippines also has a western culture and education system in the United States, with a good sense of service. English is also the best spoken in Asian countries. At the same time, affected by the industrial structure of the Philippines, the international economy of the Philippines is underdeveloped, the employment rate is low, there is no family planning policy in the Philippines, and the ratio of men to women is unbalanced (more women than men), which leads to the Philippines becoming a high-share exporter of maids, thus earning a lot of foreign exchange for the Philippines and stimulating the Philippine economy. At the same time, the quality of Filipino maids is also favored by employers. In recent years, due to the cooling of Sino-Philippine relations, the export of Filipino maids to the mainland has suddenly declined, so Indonesian maids have started to rise and enter the Chinese mainland and Hongkong markets. It is reported that there are as many as100000, and it will rise in the future.
