I miss being a millennial by their definition by 22 days and that's largely my experience.
Retirement? I've been told since HS that it is a certainty that my generation will have to work in some form until we die.
Affordable education? I'm luckier than most. I got a mostly-full ride and graduated with under $20K in debt, mostly linked to student loans for books and living expenses through 4 years of college. Of course...
Jobs? When I got out the other end, it was the start of the 1st "job-less recovery" which proceeded the economic collapse which proceeded the 2nd "job-less recovery". There hasn't been a hiring market since I graduated from college...in 2002! At this point, I'm beginning to support the notion of imposed retirement on people over 65. They didn't save? The Bush economy ate their retirements? Not my problem. 65 years old and 1 day...you're retiring. We'll carry your shit to your car for you.
Back to Affordable education...so yeah, even that small loan debt is crushing when you're perma-jobbed into fast food because the old fuckers refuse to accept that their working days are over for better or worse. The Inuits used to put their old people on ice floes and push off...it's becoming a more viable idea. Kill all the 80 year olds! (No, really...we need a governmental means to force people into retirement...economic seems best. A max age on initiation of Social Security benefits...if you don't take them by your 70th birthday, forfeit! Boost the payments to cover the losses in 401Ks. It'll be cheaper in the long run and do a bunch to encourage job-growth while tackling underemployment.)
Mass transit? I wish we as a nation would accept mass-transit. It's not my generation that believes in a "car country", it's my parents and grandparents that refuse to use public transit, oppose every public transit initiative and grouse whenever funds are earmarked for mass transit that could be spent on roads.
