I'm not denying things are better now, but they are also much more complex, people socialize way less, neighborhoods that were filled with life are now filled by cars taking any corner and you barely see anybody sitting outside and just talking.
People are way more anxious and less happy, have no kids at all.
Are we better overall? Sure. If you look at the financial angle we are.
Are we safer or happier? I don't see that at all.
