Asking this question on HN is probably not the most effective way to understand what "millennials" value, but I'll offer my anecdote.
My #1 priority is to have $10k in emergency savings. I guess that's my version of short-term savings.
Once I've hit $10k in liquid savings, I try to max out 401k and Roth IRA contributions. I am working towards having enough for a good down payment on a house by the time I am 30-32 (~10 years from now).
