That was probably a good period, though it could sustain only a few % of the current world population. Now that we have billions (due to tech development, though mostly of tech you would call very-very low tech, like plow), only mass production is capable of supporting the population. And that means all kinds of things, including the extreme wealth concentration, which is only getting worse with further tech advances. Inequality is quite likely to become the real reason of the new world war that would trim population to more sustainable levels, and a new “golden age” of recovering. For these who survived.
