Every time period in history including the one we're in now is only ever good for a very small segment of the human population.
In ancient times it was a very small group of very privileged people .... but in terms of percentage of the overall human population, I don't think the percentage has changed, just the quantity of people.
About 10% of the human population have enough wealth and privilege to be very comfortable and say things like 'I wish for the good old days' .... and 90% have some small benefits to their quality of life but absolutely do not wish for the good old days because they were much worse than they are today.
It's always been like that and it's still like that .... most of us online making these comments just never notice because we are part of the 10% of the world's population that actually have a bit of a good life. And if you think your life is not that great, try living the lives of the rest of the 90% of the world that have less than you.
