No, it really isn't. But: degrowth to a Westerner usually translates into : the developing world shouldn't develop, and meanwhile I get to keep mine. That also doesn't work. That's the kind of pulling-up-the-ladder-behind-you thinking that gets you world wars. You can have as many children as you want as a nation, but you'll have to do that in more efficient (energy, resources) ways than you did in the past if you are a developed country and you probably can still develop quite a bit if you are a developing country.
