Perhaps there is something interesting here; but what is the comparison group? I am not convinced that earlier generations had values that better matched corporate interests. We were just more likely to show up. It can also be the case that both corporate and individual interests have walked further away from each other as individuals become more hyper-individualistic and corporations become more hyper-capitalist.
"We were just more likely to show up."
I have found that this is at least 50% of being a good employee: Showing up every day and doing your job. Many in Gen Z can't even handle this.
Less of a "can't handle" and more of a "won't accept". Younger millennials and older Gen-Z are not entering the workforce with the same naivety as their older counterparts, partly due to the information age highlighting all the realities of wealth inequality and worker exploitation. These young workers are more than capable and willing to work, but they're not willing to sell their labor short beyond what is needed to survive. Their governments and companies they work for won't (not can't) promise them the same privileges that came with busting your butt even 20 years ago. Add on a precarious and divisive time for local and global politics, and it's no wonder they refuse to work for the promise of nothing but hell. The vast majority people in this demographic that manage to succeed are those inheriting money or connections.
