Holy fuck, 20k a year per kid??? That's nuts. Im pretty sure I went to UWO living at home for 4k.
Just wanted to chime in on the 20k/yr figure as I am only a couple years out of uni and have been tracking every cent spent since about 2012.
Tuition Rent Food+ Spending
Year 1 $5,332 $4,800 $18,000
Year 2 $3,946 $4,800 $18,000
Year 3 $6,900 $4,800 $18,000
Internship $7,124 $4,800 $18,000
Year 4 $5,901 $4,800 $18,000
Total = $29,203 $24000 $90,000 = $143,203
That tuition is for an engineering degree heavy on labs and therefore increased tuition costs. It also has more credit units and classes overall than a standard Art's degree.
These costs are for living off campus, sharing a condo with 2 other people and includes spending on gas, booze, food, clothing, textbooks, etc.
The only way I can see the full 160k is:
A) a premium applied to the living costs and food costs due to living in residence;
B) the parents is supporting the child outside of direct school costs as well by including a living stipend;
C) The child is going for a dual degree which may take 6+ years;
D) Zero scholarships were granted over the duration of the degree.
Hope this helps!
