Who’s responsible?

Got bored of saying it's hot and humid. A typhoon is coming. We could use a little rain.

He is a friend of my age and the only one I can call friend. He was my classmate in high school. We went on to different universities and hadn't met each other until the day of the master's course orientation when I was waiting in a line for a health check I saw him in the line waiting. I knew that he took up the master's course in my university.
We made a closer friend since then traveling together to islands, driving all around Tohoku, Hokuriku, and other resort places, playing tennis, swimming and skiing. We really hit it off. After I graduated, I entered Toshiba research center. He entered Hitachi research center. 26 years later, I quit Toshiba and I was surprised to know that he happened to quit Hitachi almost the same time. In between he got married a year after my marriage at age 32. I built my house last year. He is going to build his this year. Our paths seem to cross so often.
We met yesterday at Izakaya for the first time in a year. He doesn't drink at all. I cannot drink much. We talked 4 hours over oolong tea.
He teaches at a lower-than-average ranking university. He is having a serious difficulty in teaching students who are fatally in want of basic knowledge about science, mathematics, English and Japanese...in short, everything. He really loves teaching so he cannot bear if students do not understand his lecture. He has been volunteering a class, for which he does not get paid, in addition to his regular class, so that he can see individual students who are eager enough to come. Through this hands-on lesson some students begin to know what they are being taught for the first time. You know what I mean? Without it, they wouldn't have any idea at all about what was going on in the regular class. They are lucky to have him as their lecturer. No other teachers in the university have a volunteer class. Naturally, almost all the students leave the class room without understanding anything, feeling tired, time wasted, motivation depleted, confidence diminished. Yet they somehow graduate and are thrown into the world of harsh competition.
"Without learning anything in university, how are they going to earn money?" I asked him.
"as a clerk at a convenience store... or other. But they are lucky if they have any." He said. In fact 90 % of them (seniors) still fail to find job.
Who is responsible for this? We are.
