Sure, millennials had to come of age during the big recession of 2008, but the economy has largely recovered...and graduates today have excellent employment opportunities.
Sure, if you consider only the unemployment rate. But it doesn't tell exactly whether it's skilled work, or how well the work pays. My guess is, when you compare it to purchasing power of the past, they're not any better off despite the lower unemployment rate (which also does not include people who have given up looking for employment).
