Group 1) Those who don’t feel bad or wrong about it. These people are assholes. Group 2) Those who feel terrible and self-loathing about it. These people have problems.
Group 1 is 98% of the population. This is why we perceive people who are late as [from impolite to assholes]
Group 2 suffers because of that.
Thus my analogy with weight: 98% of people eat like starving hippos and then claim all kind of bullshit about how they are biologically|mentally|genetically|any-other-y impacted and that being fat is not their fault. And "no fat shaming because we are so special". Yes - aggressive fat shaming so that you put your shit together and stop being a (now or future) problem for the population.
The remaining 2% suffers because of that.
I mentioned this a few times in my comments
--- extra story --- I also remember a friend of mine who was overweight and had two medical conditions (ans possibly a mild psychological one) which made him what he was. I saw him fighting back - by eating healthy, moving a lot (I was lightly sparring kung-fu with him) and I was super proud. There are some happy ends - he is still far from being a model but he met a super girl (thin and sporty by the way) who realized after going past the physical aspect that he was a super guy. Their children (now teens) tease him about that.
Being perpetually late is a psychological problem. Telling people to "just be on time" is like telling depressed people to "just be happy".
Yes, depression can be remedied, as can perpetual lateness. No, it's not as easy for people who suffer from these. Please assume that if it's easy for you to either not be depressed or be on time, then it's hard for you to understand the people who exhibit these behaviors.
If you want to understand perpetual lateness better, please read this article: https://waitbutwhy.com/2015/07/why-im-always-late.html
(I would also recommend it to everyone else who is late - it's a weapon in my arsenal).
