I have kids in that Millennial generation and have had the opportunity to watch them along with their Millennial friends grow up together. Now sure, it is a small sample size, a dozen or thereabouts, but I certainly don't see any aversion to hard work, or for them trying to get something for nothing. Maybe partly because of the economic difficulties they have seen their parents go through from 2000, 2008 and now. They do seem to understand what they are up against economically.
But there are also another side I see. They want to work hard and make money, but not doing something that hurts the environment by pollution or contributing to global warming, etc. They are very much into protecting the environment in whatever they do.
In addition, while my boomer generation tried to help eliminate racism and sexism from life, they don't even see it. They don't seem to even see distinctions of race, gender, or sexual orientation in their world view. In my boomer generation we would sometimes pride ourselves in the advances in fairness to differences in race or religion. These Millennials don't even understand what we are talking about. What would race, gender or sexual orientation have anything to do with anything? I doesn't seem to matter at all to them.
These similarities seem to cut across the spectrum of those kids with conservative leanings and those with liberal leanings (usually mirroring their parents).
I see them wanting to get educated, knowing that hard work is necessary, realistic about the future, but at the same time wanting to protect their environment. A small sample size, but from what I see, they will do well and make us proud (if not even a little envious that we could achieve as much as they will).
