That's a nice sentiment for those who live in the not-US. But sadly most game development is in fact located in the US and Japan. For the US, many of the developer scene is in fact in higher cost of living areas like California, for the same reasons those areas have top tech companies and universities.
So I'm not just speaking for myself when I say that your estimates do not compare to most minimum wage work, which has itself already ceased to be a "living wage". It could certainly shift, but those are the current breaks. Your favorite indie games are likely made by North Americans as of now, and their survival depends on their ability to survive in North America. The one exception I can think off the top of my head is Team Cherry in Australia, which is not in a much better CoL situation if they are in the cities.
American or not, I don't think the solution to finances for online development is to emigrate out of your home country, away from your community, life cultures, and overall lifestyle. Tech is a big enough part of the US economy that everyone doing it would weaken the dollar itself, and then everyone loses given the current way the world economy works.
