After that you might have heard people mention Canadian options like McGill and Waterloo, and then MAYBE a handful of European options in Germany and Switzerland.
But the Sorbonne was distinctly understood by a majority of peers for its status.
In France, La Sorbonne isn't considered particularly prestigious. Grandes Ecoles (ENS for research across various topics but especially science; Polytechnique for engineering; HEC for business; ENA/Science Po for politics) are considered much more prestigious and elite (getting there is harder than for La Sorbonne, you have to undergo 2 years of prep schools and then take an exam, where only the top scorers get into these Ecoles), and will get you the higher paying jobs.
Outside France, seems that these Grandes Ecoles don't hold much prestige against La Sorbonne which seems to be considered more elite.
Harvard, on the other hand, lets in a few thousand students a year and I am pretty sure that has barely changed for decades. This changes a ivy degree from not just a good degree to a good degree with a high elitism and increasing scarcity associated with it.
Like a lot of things in Canada the bell curve is flatter -- but it doesn't mean there isn't a bell curve.
But the difference is that in the US, it's pretty common for families or students to aspire to the "best". That's true even in middle and low-middle class families. That's something I never saw in Canada.
That kind of thinking in Canada is limited to the upper class and old money in Canada.
Nobody? I think what you mean is "nobody in the middle class cares". Clearly they are very prestigious universities in Europe (Sorbonne) that open doors other universities don't.
What I've noticed in the US is that the middle class (and even lower) aspire to the top colleges. In Canada? Not as much.
