"Any more" and "these days" only imply an arbitrary amount of novelty. They are correct phrases whether we're observing a problem this year that wasn't present last year, or this millennia that wasn't present last millennia.

Regardless, novelty is a straw man. The implication that it's wrong to complain about something because it's not new is fallacious.

Yes, a person may compare younger people unfavorably to their own generation at the same age on some property they observe to be different when in fact it's only their perspective/memory that is different. But demonstrating that a complaint is not new is not evidence of that.
