Why don't tech salaries decrease come graduation season when hundreds of thousands of college students majoring in CS move on from college and are about to start working? Or why have tech salaries grown as much as they did when CS major enrollment kept hitting record highs throughout the late 2010s?

Salaries are a function of supply and demand. There's a huge amount of demand for these skills, and a new graduating class doesn't change that significantly (new grads aren't very productive after all, and salaries don't change that fast, since people don't change jobs every month). And demand has been increasing, faster than the new supply.

But there's probably other variables too. Why are tech salaries so low in Canada, for instance, despite there being lots of demand, and not that much supply (with many Canadians trying to go south to get the higher salaries there)?
