Unless you mean globally, in which case it's near impossible to tell. But GP likely meant the US or Europe.
Reminds me of movies "Aliens attack Earth. By Earth by obviously mean USA. By USA we obviously mean New York City. By New York City we obviously mean Manhattan.".
Half of Europe was literally undergoing complete economic collapse in 90's.
"I can't stand the conflation of "satisfied" and "happy." It's insane. There is more happiness in one Zimbabwean (country "happiness" rank: 143) than in one hundred Icelanders (country "happiness" rank: 2, worldwide antidepressant consumption rank: 1.) Go stand in a crowd of people and count the fucking smiles and the fucking laughter.
"It is all part of this broader wave of newspeak. If you can quite literally redefine happiness, you can redefine anything. Nothing has meaning anymore. You will live alone, you will consume antidepressants, you will be protected from the sunlight, you will not smile, you will not laugh, and you will be happy." [0]
As someone who grew up in a rural area I don't miss it and I think people who call it a good standard of living have interesting criteria. That cheaper rural home also comes with secondary costs, like a longer commute.
