My lifestyle would have been essentially unchanged from that of my ancient grandparents and great grandparents. Prior to about the middle of the 18th century, economic growth was so slow that it was often imperceptible within the span of a lifetime. The staggering growth of the last two or three centuries has supported a huge increase in population.
And, in the West, ours is the first age in which affluence has been enjoyed by more than just a tiny fraction of the population.
