We can see that with food: as soon as the shaming of people for being fat weakened, as it happened primarily in the US and then in the Western world at large, people started to indulge without guardrails.
We can see that with clothing and appearance: people started to dress slovenly, preferring comfort to being presentable and well-put together.
We can see that with "productivity": people started doomscrolling for hours or watching hours upon hours of life lived by other people, instead of living their lives.
I disagree strongly. I think most people do the best they can. When they are emotionally overwhelmed, they withdraw.
Doing things you dislike, such as dressing certain ways, is not slovenliness. Your opinion is meaningful only to you (and those who choose to share it), it's not a standard. Also, what data is there of a problem? When people started dressing more casually (which I guess is your objection), the economy boomed, freedom boomed, Silicon Valley - famously casual - boomed, etc.
We could say that your thinking is slovenly, too lazy to try to understand that others have very different thoughts, perspectives, and priorities which are just as valid as yours. Too lazy to try to look at evidence. Much easier to take the egocentric path and judge everyone else, and repeat misinformation that's appealing - and all especially easier when it's culturally enabled.
The way that the comment I am answering comes across is quite reactive in nature and too forceful in tone. Nowhere I said that people should dress in a suit or sundress or that they should have visible abs. I do, but that is just my preference.
I just expressed my opinion that, when left to their own devices, people are often apathetic. Or maybe, as the writer of the comment suggested, they (some, to be clear, but in my opinion, too many) choose to be 400 pounds, not showering, dressing in PJs, or doomscroll, because that's the way they are happy.
Good for them, they surely live a life of fewer preoccupations.
