I grew up in the same time frame. I see today that a BS chemist starts at about $40,000 but tuition alone at the U of Delaware, where I went, is now $52,000. When I was there tuition was about $1,000 for 4 years with a starting salary of $6,000. I made enough money on summer jobs to pay for my education and still pocket a few hundred. Grad school was paid for with a teaching assistantship. Pretty hard to do this today.
But, college today would be a lot cheaper without the influx of money and students. It's a matter of supply and demand and universities are examples of unbridled capitalism.
