But they also supposedly earn less. My point is that there are options to save money. The problem is bigger than having to increase wages.
In many cases someone will settle for a very low standard of living, and set aside a small amount to support family living in a country with a much lower cost of living.
Now, what is a low standard of living? We know that the world doesn’t have the resources to let everybody live like an average American. Sooner or later, resource usage has to be reduced. Everybody will have a very low standard of living unless we figure out how to live comfortably with less.
In objective terms the lifestyle framed as the American ideal is unsustainable and inequitable, but much of the material value of the lifestyle carries little value in relative terms for genuine well being. Planning the built environment, cooperating in the community and workplace, and sharing benefits and burdens across our lives, would allow us to achieve a very high standard of living for everyone at a much more reasonable material cost.
I am not understanding the general theme of your various comments in relation to one another.
