College is a subject near and dear to my heart (and career).
My first semester at Trenton State College (in 1968), cost me $175 (tuition) plus about $40 per month in off-campus housing rent.
I remember the numbers because I had to borrow that money from my aunt (and it took me about a year to pay her back).
One of my younger brothers graduated from Harvard. He went for free. And not on a scholarship either. At the time, he figured out that if you were an employee of the college, you could take night classes (and certain day classes) for free.
So he did. And ended up with a Bachelor of Science degree.
When you come from a large, poor family (7 kids) you have to be creative.
Both of my parents left school before the age of 13. But all of their children ended up with advanced college degrees.
These days, my response to the cost of higher ed is to look at your local community college.
~My school~ is one of the most expensive community colleges in the US. If you're careful, you can get your first two years done at CCM for about $6500.
Of course, lots of folks might question the quality of a community college compared to a "real" school.....this is often backwards. I've sat in classes at Princeton, Rutgers and others. Most use the same English Comp book and Calculus book that we do. And many freshman classes at four-year schools are huge (100+ being common). Our classes are rarely more than 25 and our teachers are usually full-timers with lots of experience. Many freshman-level "teachers" at four-year schools are foreign graduate students, who may be smart, but unable or unskilled at conveying subject matter.
In the old days, there was questions about transfer of credits from community colleges to four years schools. But most states have inter-school agreements these days (for example, NJIT is contractually liable to take any of my engineering students with a 2.5 GPA or better).
Of course, none of this applies to <span style="text-decoration: underline">for-profit</span>, two-year schools (often called "trade schools"). They are a different deal all together (in other words, <span style="font-style: italic">buyer beware</span>).
Finally, there's is only one place in the US where you can take College Physics with Dr. Einstein. Not Harvard, Princeton or Yale. My community college.

I've worked with Dr. Fred Einstein for 25+ years. Not surprisingly, he's a great teacher. I "talk shop" with him all the time (and yes, he's related....he's a second cousin).
