My overall point is that of course your cost of living will be lower when you consume a lot less.
And I disagree that the quality of life is the same for someone who lives in a nice house vs small apartment, has to use public transport vs personal luxury vehicle and so on.
Yeah, I get that people have different thoughts and priorities on what is luxurious to them. That makes sense. I'm not really a car person since I grew up needing one for 30 years in LA finding parking multiple times a day. I just wouldn't make too many assumptions about how things work over here. Not sure why there is an assumption that I live in a small apartment. Big houses are also cheap in the suburbs over here :) You should visit sometime!
