I totally agree with all of those points, I was just providing some anec-data that it does happen.
I paid my tuition almost entirely through co-ops (6th month internships) and then worked while in school to pay my day to day bills. I was also very lucky to have a safety net from my parents if I needed it, although I didn't.
Having the "living and supportive family safety net" is definitely under-appreciated as an advantage here in the US. Many who have it don't even realize what an advantage it is.
