Just because it applied 2500 years ago it doesn't make it not true. I think there's some fallacy that people can cite that this happens most generations and then indicate that it must not be a true thing.
What's closer to the truth is that each generation hopes to make life easier for the subsequent generations. The effect of that is all of the things that we complain about. More than one thing can be true at the same time. As things get easier people get lazier. It is only a natural thing. That can be demonstrated over and over in society. That can be demonstrated over the generations. So what was true 2,500 years ago still is true today.
