There are a lot of these types in my field now:

I do think the commenter is exactly right about how we get so many people ill-suited for IT — all they experience is some IT person coming to their desk, clicking on something they could have clicked on themselves (if they had known what to click) and then assume that’s the entire job. In reality that’s about 0.1% of the job. However, they never see all the other background tasks that’s not that single click.

So they get some certs and enter the IT field. The certs aren’t enough and they are truly incapable doing the work but get hired somewhere anyway. They end up repeating the same year of experience 10 years in a row and never progress. Then they wonder why they are passed up for promotion. But it’s no mystery; our field is full of these people who should’ve never gotten into it because they simply have no talent for IT and couldn’t troubleshoot their way out of a tissue paper box with a plasma torch.

This field does indeed pay well but only if you can get past the tier the folks I’m talking about above inevitably get stuck at.

This is also in large part explanatory regarding the lack of troubleshooting skills in those 35 and under.
