It'd be funny to change some of them and show the problem as being caused by the companies. Instead of "Great job openings, no candidates" it could be "Great skilled workforce, no employers". https://money.cnn.com/2009/11/03/news/economy/jobs_sit_open/...
"On the same note, though perfectly correlated variables are redundant and might not add value to the model (and if removed, would be computationally efficient), a high-variable correlation could have additional information to add. In other words, two variables that are not correlated could still be of importance to the model. When in doubt, it’s safer to train the model and observe it’s performance."
The "In other words" part seem to talk about uncorrelated variables while the sentence before that talked about highly correlated variables. I always thought to discard one of two variables that were highly correlated.
