College does not need to be more like a trade school, that's what trade schools are for. If we need to churn out a gaggle of programmers the boot camp model has worked for years, Accenture used to push hundreds of college grads through their program in the 90's and out popped VB programmers. Now dozens of places provide the same service at a cost and in 12 short weeks you can become a "full stack" programmer. None of these people have a clue what is going on under the curtains but most run of the mill programmers don't need to know what is going on under the curtains. If you are interested in how things work and why they work that way going to a university and studying CS might will that need, but it involves a lot of math and other classes that you will likely never use in a workplace.

This is just a simple misunderstanding of what college is for, expanding one's knowledge for the sake of expanding one's knowledge -being a good programmer is not the intent but it might be a by product.
