One thing is for sure, if Quebec can afford it, you folks can!
On a serious note, I think most of Quebec's education system is payed for by Quebecers with provincial income tax, which is pretty high. Of course, Quebec receives equalization payments. But please show me the math that demonstrates how Quebec is stopping other provinces from lowering its tuition fees. Are we really stopping you from anything at all?
Do you want lower tuition fees in your province? If so, what stops you from getting them?
Didn't answer the question.
