That's not surprising, considering that current college students did a lot of their growing up in the aftermath of the housing crash. It's kind of unfair to chide them for being preoccupied with financial stability (or for claiming to be when asked, not the same thing). Meanwhile, what's the messaging like about college today? That you should drop out to start a company, and that if you're studying anything not STEM related you're kind of a dope.
But really, in the link "helping others" is a close second at 65%, only a point behind the boomers and two points ahead of gen x. So, there goes declinism. Millenials are only about 4 points higher than gen-x in "well off financially" (70.8 to 74.4), hardly a generational sea change. The real difference is with the boomers, who come in at 73% "develop a meaningful philosophy of life" and 44% "well off financially". Perhaps rather than rejecting helping others, every generation since the boomers has rejected the solipsism it takes for a college student to list "develop my philosophy" as their primary goal.
