Quiet Quitters and Productivity

Survey datashows that job dedication among young people is far lower than for older generations. Is this due to their upbringing--that what's important is me and my happiness? Or is it due to the fact that older people tend to be managers while young people are individual contributors? My experience is that it's far easier to be dedicated to your job if you are the one calling the shots versus the one taking orders. If the latter, it suggests that we are going to see very slow productivity growth going forward.
