Education is never useless. Today's political landscape shows me how desperately lacking in critical thinking skills many Americans are.
Many student loans are for technical and vocational programs, and the jobs of the future require some post secondary education.
An uneducated populace is a populist demagogues dream and a real world nightmare.
Education is useless if you can't and don't use it. Education rarely teaches critical thinking skills. They teach subjects. And depending on what you are taking it might teach you some critical thinking regarding the subject such as engineering. But that doesn't mean you are generally a critical thinker.
I've met a lot of very knowledgeable and educated people who were good at whatever they are doing, but their critical thinking only applies to their specialty. Not anything else.
And there are plenty of subjects that only indoctrinate you into leftist ideology and don't allow for critical thinking.
If you are talking uneducated like reading writing arithmetic, history and those kinds of subjects then I agree, that's a nightmare. There are things everyone should be educated on. If you are illiterate that severely limits you. But you certainly do not need half the stuff you are taught in school. Like Gender theory or CRT. I went to college, my wife went to college, one of my daughters went and both my sons. And we've all taken a lot of useless classes that don't have a lick to do with our lives. And everyone paid a lot of money for it.
I also have friends and family who didn't go to college who are doing very well with their lives and are making and have made a good living.
College as it is is in no way necessary for a lot of things. For some it is, like being a doctor or an Engineer. But even at that there are a lot of wasted classes.
College would be cheaper and take less time if you could focus on your profession.
I know a lot of very smart, critical thinking people who never went to college. And a lot of people who have no critical thinking skills who went.
