I can understand that because you are not the first college professor I've interacted with. You had one chance to say something and yet you left it as an afterthought. That is the proof of your bias as a professional academic. Instead you have made an excuse that somehow your bias is inscrutable and are covering it up with more pedantry. The neoliberalization of academia extends to the attitudes of its people who reproduce its culture and clearly you are behaving consistently with that. Bear in mind, as a professor or instructor you are much more likely to hold these unchallenged biases because people like myself who have been through the process of advanced academia at elite Western universities yet come to reject the system are not likely to be interacting with you within the system any more, so you are literally not receiving certain information.
And rather than reiterate, I shall elaborate on my original remark: you had stated "students are not used to doing the necessary work". You want a "system that prevents cheating" which is again full of backwards presuppositions and implicitly value laden dependency on a narrow-minded perspective. What you don't realize is how loaded such statements are, you had zero problem making those utterances. You might as well be a 60 year old centrist Boomer to say something like that so casually. It is completely oblivious to contemporary social problems. You surely have seen how racists and misogynists behave when they unwittingly say things that reveal their casual bigotry? So, I can know your mind, which is that of a typical professoriate who doesn't stay in their lane when their sociology, education, and related departments actually have something to truthful to offer in understanding this issue--the neoliberalizatiom of academia--while you are just talking out your prejudiced ass.
Finally, that other commenter said it a lot better than you. That's why I was replying to them and not you.
