I know every generation thinks the young generation is lazy, etc., but there is real statistical evidence that the Millennial generation actually is starting to work much later. On a more anecdotal basis, I notice a very different approach to work in my kids (late teens, early 20s) and in their peers. My kids have always had to do chores and work around the house so I don't think that's the difference.
They do things like decide they're unhappy with their current employer so they just walk out, without trying to fix the problem and without trying to find another job first. I have never in my life quit a job before finding another, and it wouldn't even occur to me to do so. If my job sucks, by all means I'll make a move, but not until I have something else lined up. That's just one example, but it's typical of their whole approach. I suppose in some ways it's good to be more focused on quality of life and less on income... but not until you're safely self-sufficient.
It concerns me that I'm wandering into "get off my lawn!" territory here... but there really does seem to be a difference, a worrisome one.
