While agreeing with you i think the (non)issue the article tackles is population shrinkage. We hear all too often the concerns that we (western countries) have aging populations, incapable of sustaining the Social State.

This in my view stems from an political/economic paradigm that can only function in perpetual growth. In it, perpetual growth is the alibi for not redistributing, ever, because you must first create wealth and only then, in the future, we can all live better lives.

All in all, as you point, is a matter of avoiding redistribution, that starts home and affects distant poor countries.
