Why would it need to be a co-coordinated effort? I think you will find it is just the prevailing opinion in regards to the future scale and efficiency of humanity. That is something people on HN love to think about so it is no surprise they have come to similar opinions. The facts are dire for the things you mentioned as "western ameneties".

Do I wish that weren't true and that we could all have affordable family homes to live on? Sure, but suburbia doesn't even make sense from a commuting point of view let alone environmental.
