What does "used to ain't the same as ought to" mean?

"Used to" isn't the same as "ought to". Just because they are used to sleeping in those conditions, doesn't mean they *should* be sleeping in those conditions.

"Just because you're used to sleeping poorly, doesn't mean that that's how you should be sleeping."

Paraphrasing: "Just because you are used to sleeping rough, doesn't mean you ought to sleep rough." Or with clearer punctuation: "'Used to' ain't the same as 'ought to'"

Familiarity is not the same as requirement. Do you understand? Being "used to" something means you are accustomed to it. "ought to" means you *should* behave in a certain way. Just because it's normal for you to "sleep rough" doesn't mean you should always sleep rough. It's implying that Viv should not have to tolerate poor conditions merely because he has had to do so in the past.

others have explained ought quite a bit, but I'll throw in a tidbit about "used to" (pronounced "yoost") "\[noun\] used to do" = previously did regularly "\[noun\] **am/is** used to \[noun\]"/"\[noun\] am/is used to do**ing**" = accustomed to doing/having/experiencing if pronounced "yoozed", then it's a conjugation of "use" and "\[object\] is used to do" = purpose, and "\[noun 1\] used \[noun 2\]" = operation of \[noun 2\] "I used to go to the liquor store" = I previously had a habit of going to the liquor store (implied: but I don't anymore) "I am used to going to the liquor store" = I'm accustomed to going to the liquor store "This credit card is used to buy stuff from the liquor store" = that particular credit card's purpose is to buy things from the liquor store. It may have other purposes as well, but that is the relevant purpose right now. "I used this credit card to buy rum from the liquor store" = I bought rum from the liquor store and paid with this credit card. "I am used to using the liquor store as an example for random things" = I should probably re-evaluate my drinking habits {joke}

What on earth, I see "ought to" for the first time 🫣

Used to: that what was common practice, what "everyone" did in those days Ought to: how it should be In the past peope regularly did something that was accepted then, and done by a lot of people. This doesn't mean that we should do it now. "Just because in the first half of the 19th century Aftican Americans used to be slaves, doesn't mean they ought to be slaves" "Used to be slaves Doesn't mean "Ought to be slaves" (in the meaning that it would be better if they still were slaves)

"used to" - as in being accustomed to doing something - is not the same thing as "ought to" - as in being obligated to do something. In other words "just because that's you normally do, doesn't mean you should do it"

"Just because you're familiar with doing it, doesn't mean it's a good idea," probably captures the intended meaning the best. It's not about obligation here, just about having the right idea or being good for you.

This is an amazing Southernism, and thank you for bringing it to my attention. "Yousta's one thang; oughta's another"

Just because you *have* done something (in the past, hense the “ed”), doesn’t mean you *should*.

"ain't" is slang/improper for "are not", "is not", and similar negations. "ought to" here is similar in meaning to "should" but indicating more of directive (often moral, but doesn't seem to be so here) rather than a suggestion. It also tends to be used in more archaic speech rather than modern. It's been a while since I read this book, but using "ain't" and "ought" in the same sentence is a bit jarring if you pay attention to the details and makes Cal's word choice seem all over the place.

"Just because something existed doesn't mean it should have existed or should exist today"
