Oh, at no point did I mean to imply that all courses at all colleges taught at all times everywhere are exactly identical to high school courses of 30 years ago. I'm sorry I wasn't perfectly and absolutely clear on this point. That's certainly not the case, and it's absolutely true that there do exist courses that have no high school equivalent 30 years ago.
Let me say that again because I know you won't get it the first time: yes, there are subjects that didn't exist in high school then that are in colleges now. But when it comes to topics like English, math, geography...basic knowledge, then, yes, college now is what high school was decades ago.
think that says more about the courses you're teaching/school you're working at (in your defense, the first year of major courses was pretty introductory, and all my GEC courses are basically topics from highschool on steroids and covered in much higher detail in much less time). Here are some of the topics I took courses in last year (undergrad): formal languages, finite automata and turing machines, graph theory, numerical approximation, and analysis of algorithms. Sound like any highschool from 30 years ago?
So, your GEC courses (2 years) and first year major courses were similar to high school--harder, perhaps, but that would probably be because of going to a weak high school...that's a good chunk of a 4 year degree, in my opinion, and, in my opinion, Tulane and LSU are sort of high end schools. Anyway, if you're in a crappy high school, a year of crappy high school work would be perhaps 3 week of college work, so when you say stuff like this, you're agreeing with my point.
Note that I took a graph theory course in my high school, and other courses addressed some of the topics you listed, although I'm hard pressed to say if they were exactly identical in all ways, as I didn't take them...in your defense, my high school had 3000 students, and probably had a wider curriculum than most.
I'm sorry I don't have God himself (about the only source that has even a slight chance of being accepted), but here's one article refencing a Zogby poll on the topic (it cites a CNS news article, which, regrettably, I can't find directly, and lists questions if you read the responses):

Again to emphasize, I'm certain there are exceptions. I'm merely speaking from direct observation of general trends and
studies.
