I don't think it's quite as black and white as that.
I was trying to suggest that investments in post-secondary education are indeed an investment. We know that graduates of colleges and universities earn substantially more income than people who don't graduate. As a result, they pay higher taxes. There are a variety of ways of generating future revenue to meet our needs. Paying down the debt is one of them, but investing in post-secondary education is another one.
And how do we balance that?
