It’s not just millennials. I was born 5 years after the end of the Baby Boomers and by the time I was 20 everything was becoming out of reach. Add a energy crisis or two, 40 years of Republican austerity for anyone but themselves, and a few financial crashes We the People ended-up bailing out, and I never got anywhere enough traction to do more than just get by without a mountain of debt. We never outran the entitlement of the Boomer generation.
Good luck Millennials - and I mean it - but the only way out is to get out of the US while you can.
