Firstly, it's very nice that there are people like you, I respect your choice and your path!
At the same time, I will add that you did not quite understand me correctly. I was not talking about changing the place of residence or abandoning poor relatives, but about the fact that for personal development it is necessary to communicate in a more "developed" society, which will increase the level of knowledge, gain quality experience, and gain access to great opportunities. All this can be used to solve a host of problems - from attracting investment to poor areas, to giving people from, no offense, a less developed stratum an opportunity to make an attempt to raise their living standards! Like any "tool" - knowledge, experience, connections can be used in any way - for good and for harm, for many or only for oneself.
For a better understanding, a simple example - it is difficult to learn, for example, English if you only have a dictionary, and much easier to learn if you find yourself in a language environment, for example, in Britain or the United States. And when you raise the level of the language - you can use it as you like - you can find a good job in this country, or return to your country and start a business with international partners or for their market, and invest money in your city, or in their relatives.
Now that I understand you, how about a middle way that would be both good for your view and good for my view as well. We now have internet under our hands, internet is very easy to access even in some of the worst countries in the world, my country provides one of the most expensive (compared to minimum wage a standard internet is 10% of minimum wage) for speed that is funny, it literally takes a minute for me to open a webpage sometimes, I have under 10 mbps for that much money.
However we still have access to it. I never went to anywhere else in the world, and yet I can speak English "fairly" well, sure I am not a native speaker but here I am writing on this forum and I rarely get complaints on my English, so you can learn English wherever you are as long as you want to. The middle way offer : Stay in your country but work online with other nations? Freelancing basically, or startup, or whatever you want online, that way you work with foreigners and get education, network, partnership, business, money from them but you are not leaving your nation neither.
