Why does everybody need to speak English?

Hello everyone, I'm a Chinese and Chinese is my native language, I can't speak English properly. But it doesn't matter if I don't get out of Asia, because Japanese, Koreans, Thais, Indians, Vietnamese, Singaporeans, Australians, Indonesians, Malaysians and Filipinos have English-speaking service for Chinese all over Asia, many Asians can speak English as well, but now I'm in Spain and the problem comes, a lot of Spanish disdainfully say they don't speak English, that's fine, I know English is not their mother tongue, but I don't like their attitudes, they should at least try to communicate with me. I did nothing wrong to not speak a little bit of Spanish, I've never seen any European countries, I've never been in Europe, I should learn a little bit of Spanish before coming here, but I'm not sure if I will ever visit Spain or other European countries. Why does everybody need to speak English? If I'm a Spaniard, I wouldn't learn English as well, English is not widely used in Europe, Canada and South America, most of them use their native languages, unlike Asia, most of us don't have English as our native language, but English is widely used in Asia, many Asians can speak English as well and English-speaking service for Chinese are everywhere in Asia, especially in Malaysia, Thailand, Singapore, Vietnam, Indonesia and the Philippines and India, they're a lot of English-speaking Indians in Asia, many Chinese learn English at school, I knew some basic English when I was 10. I don't like the way Europeans look down on us, many Asians are rich, many Asians have a high education, many Asians work for world-class enterprises, you say you disdain all the stupid Asians who leave their countries just to make money, but some of them are students, some of them are immigrants because of wars, some of them work for world-class enterprises, some of them run companies, some of them are rich, many of them are poor, they try to get better lives by leaving their countries, but you disdainfully look down on all of them, you guys have better lives than they do, you don't have to leave your countries, everybody has a reason to leave their countries, you are just the lucky ones, you guys are born in developed countries, you guys have better lives, you have no need to leave your countries, but you guys are born in third world countries, you guys won't stay, you guys will leave your countries, if you were them, you guys would also leave your countries, so stop looking down on all the stupid Asians who leave their countries just to make money.
