That might be fine for someone in the wrong college degree, but I - as a tax payer - need every sixth grader to learn essential the same things. I need kids to grow up able to provide life support for themselves so I can retire as by body fails from old age. I'm investing in the future of many kids I otherwise don't know or care about because making their life better makes mine better.

Even in the case of a college degree some are better than others

Depending on what you mean by "school" I'd disagree. Voluntary tertiary education makes sense, not all chosen professions may need or benefit from a degree.

But primary education needs to be a requirement for every child. Coming from a country with a large illiterate population, it's easy to see how hard their lives are compared to folks with an education but similar socio-economic backgrounds.

Now obviously implementing universal primary education and the details can be debated and need to be context specific.

They were already at a University. None of the students were required to be there. They all had the ability to just leave.

There has been a shift towards too many jobs requiring a tertiary education.

But good luck reversing that trend.
