I mean that would be true in the US, but OP explicitly said he's not in the US. It really depends on where he is; 1.5k/month could be considered a very good wage where he is.
OP stated he wanted to work remotely, hence he's competing in the global (remote work) market. Many US and other companies hire in this market and often pay US-level (but generally not Silicon Valley-level) salaries. A lot of digital nomad types have those jobs.
Judging by OP's good grasp of English and the fact that he reads Hacker News, I'd say that alone makes him more qualified for those jobs than the bulk of developers from his country. I'd wager many of them don't even compete in that market to begin with.
Agreed. 1.5k/month is almost upper middle class in my country.
But if you're competing with the US market, no reason not to aim for 15k/month or even 150k/month while you're at it.
Then you can take some of your earnings and invest it in your local economy. Help friends start local companies, etc.
But I understand what you're saying.
