While what you say is true, housing is becoming an issue pretty much in every first world country, purchase power for the bottom 50% percentile is at historical lows, young people have issues entering a job market, retirement age is constantly pushed exacerbating the difficulty's young people have in entering the job market.So, yes, quality of life is increasing in some dimensions, but it's also drastically decreasing in others. For instance, until I manage to purchase an house I felt very stressed about renting for my whole life and owning nothing of consequence. This impacted severely my mood and indirectly my quality of life.
