What is "high standard of living" anyway? How many yachts and airplanes is it? How many cars? Other modes of transportation? Average kilograms of stuff owned and used per person? Living space? How long you have to travel to work or how far? How much do you strictly have to work to live at that level, if linear scaling would be sufficient? How much energy, thermal and electrical is used to sustain and separately embodied in production of your stuff? Etc. Once we define the threshold of high standard of living, we can optimize for it. This is literally when we say "nearly nobody can live as opulent as this" and can condemn waste. Feel free to pick say 90th percentile or something.
