I'm generation X. The similar things were said of us. My generation came back home after college (or least I did for a little while). We were called lazy, and slackers. Which was a term at the time.
My parents are baby-boomers, they were the hippie flower people. They were not liked by the previous generation. That just seems to be how it goes.
Gen-Xers didn't have the obvious options to not work at a normal job, as your generation does. We just knew we didn't want to work 40 years.
I didn't get married have kids until my 30s, which became more normal for my generation, and is normal for yours.
There was a lot of discussion on how to communicate with Gen Xer's in the workforce, just as I see for millennials.
What your generation has that mine did not have in their 20's was more options to make money online. Ebay, which is old now, was radical and game changing in 1995. I made money in graduate school from eBay. And people made fun of me for it. Now people wouldn't blink at making money online.
I also started my freelance video work in 01. Some people made fun of me for it, calling it a "hobby". Never mind the fact, it brought me cold hard cash. Now-a-days that would be called your gig or side-hustle, and wouldn't blink an eye about it. That's a difference I notice.
I work with several people your age as teachers, they're just fine.
In 15 years you'll notice people complaining about the useless generation behind you.
That just seems to be how it goes. One generation complains about the next.
