I don't think anyone is arguing that we remove liberal arts from the K-12 curriculum. There should be more to education than just vocational training, especially at the younger grade levels. If we want to have a functional democracy we need educated voters, and they should have a broad base of knowledge including the liberal arts.

At the college level I think the colleges themselves are to blame for all the animosity towards the liberal arts, they've priced themselves completely out of the market. Not too long ago it wasn't a big deal to spend four years getting a liberal arts degree and then going on to an MBA, Law or sales or even a STEM field to make a living afterwards. That's exactly what the author's wife of this article did by the sounds of it. Now that path might mean tens of thousands of dollars of debt just for the BA, so the pressure is on to make that investment worth while and for many it's not.
