You get what you pay for.
I've lost count of how many students show up in my classes completely thunderstruck that I grade papers both for content mastery and for word-by-word, sentence-by-sentence proofreading. What I've heard over and over again is that in their community college writing classes, the written work comes back with a check, or with about three sentences of global comments, but that no one ever, ever makes them take apart their writing, fix it at the most basic level, and put it back together again. Those students get Cs and Ds in upper division classes, and are refused admission to graduate programs, because, never mind what CollegePlus put on their transcript, they simply don't know how to write. Some of them go back and take the writing classes again on our campus, where the faculty do whatever's necessary to teach mastery, including individualized attention and tutoring, instead of going through the motions for fifteen weeks with a lecture hall full of half-awake faces, or putting self-grading modules up on an LMS.
Years ago, a good friend of mine took a weekend trip to Mexico to get lap band surgery, because it's so cheap there. After nearly dying of internal hemorrhage, spending six weeks in an American hospital piling up bills, and getting fired from her job for the amount of work she missed, she conceded that cheap isn't always cheap. I know the argument "Pseudo-teaching I can afford is better than teaching that'll put me in debt" is appealing, but I've seen how it plays out in the life of too many students to put any stock in it.
Now, I freely admit that there exist a few basic classes that are taught the exact same way in an AP class and at Harvard, and for material in that category, it makes sense to go the cheapest route. But that has a lot to do with the student's major. A math or engineering major might do just fine with a community college freshman history class, but I sure wouldn't recommend shortcut history coursework if they wanted to major in Bible, or in any fine art, or Literature, or Rhetoric and Public Address. It goes without saying that if they want to be a history major, that foundation had better be of the finest quality they can get, but the same is true in all the fields I listed, and several more. If you want a good read on what classes you can get away with picking up in a sub-optimal setting, talk with a faculty member in your area of study. But the notion that "If it's core, then any substitute will do" is very unwise.
Last thought: none of what I'm saying is aimed in a disrespectful fashion at community college teachers. I've taught community college classes before, so I know how hard they work, by and large. Most would agree that in the big crowd-control classes, they're not teaching at all. They're dangling content in front of students, and the ones who didn't need the class in the first place will pick up a tip or two. The rest will get about as much education as the evangelizing an atheist gets driving past a church.
