I’ve heard all this before when as a fresh-out-of-college gem-x’er back in the late 80's. I was told that I’d never reach my parents level of income or even be able to afford to purchase a house. All BS sold to my by the Media. I’m not surprised the narrative is unchanged almost 30 years later.
My only advice to the “put upon” millennial is to stop whining and get a job, then build a career.
My other piece of advice is to major in a STEM program at university. You’ll have a chance to gain employment you can build a career on.
