This is just an observation. YMMV, of course. But I've noticed this with increasing frequency in recent years...
It's not necessarily a "new" thing. Lying certainly isn't new. But I imagine there must have been a time when, hypothetically, you could make plans with someone, or discuss something, and they would damn well hold to it/keep their word...
Like, in my observation, this happens all the damn time: people flake, people change their mind at the last minute, people ghost (and I do it, too), people, worst of all, change plans, or change their mind, and don't even tell you...
I'm not talking just with women, either. My male "friends" do this. My family does this. Constantly. Randoms I meet, and plan to meet up with later, do this too. And sure, I'm a common factor, but I see this happening more generally, to all manner of people I know, too.
I really, really wish that we "as a society" hadn't normalised this... "Flaky", noncommittal, "my needs come first, always" bullshit...
I really, really do.
If there's a culture where keeping your word and actually committing is still the default, I look forward to one day finding it. Because I am yet to really... Ever experience that. And I've travelled fairly widely and met a lot of people.
Honor, integrity, self-sacrifice, accountability and consequences are all lost concepts in the new world. Hedonism, self-love and self-gratification are the new moral virtues of the new religion.
It used to be that calling someone a liar was an insult worthy of a duel to the death. This is because your word meant something. Nowadays words are cheap and nobody bats an eye to slander and insult others without any justification or reason behind it.
Words were more scarce and more valuable, and the insights of people with experience or insight were greatly valued. Nowadays everyone feels entitled to have their opinions heard, and people feel encouraged or even obligated to have strong opinions about everything whether their opinions are worth anything or not.
Morality was objective under Christianity, then it became relative to tear down Christianity, and now it's purely utilitarian, specifically in respect to the political power of the high priests of the new religion. Morality, meaning, language... everything now serves the new religion. It's truly dystopian.
