This is true. People talk about the generation after them being weak and pathetic. That is parents just slagging off their kids. I guess it is the classic line like about people who have nice immigrant neighbours hate immigrants but say “no I don’t mean those ones. Those are okay. It is all the others I don’t know”Old people moaning about the "ways of today" based on selective nostalgic memories of how they felt things used to be is a timeless concept.
As usual the answer is: if people are weird and bad today, its your fault because you raised them and built the society of today.
