I'm not certain but I think we're in perfect agreement here. The environment in which people live has changed and I think that should be the obvious first target to change.

I think this urge to blame people for the effects of their environment seen in the one of the parent post is an example of a very dark part of our attitude toward change. It is very easy and tempting to short circuit into ridiculing positive changes in favor of instead attempting to fix it by punishment/shaming ("People will literally rezone entire cities rather than saying we need to eat less food and workout more")
