Note that the effect goes both ways. Companies started offering ridiculous pay package to less-than-qualified people, ... because the others were doing it.
Trend following is a real nasty human aspect, social media platforms know that too well.
It's so much easier to follow what others are doing than buck the trend and have to justify yourself at every corner decision. Remember the old saying "no one ever got fired for picking Oracle". Well today you'll hear me say "no one ever got fired for picking Salesforce".
Today's industry is plagued by a swath of people coming from all industries into the IT industry, because theirs is shrinking, and because money keeps flowing in this one; pure and simple.
No one really knows what the heck we're doing anymore, and everyone is risk adverse, flows down like the river; because it's impossible to justify yourself in large businesses for bucking the trend.
You'll do better if you can somehow buck the trend at the pivotal points, and read between the lines, but I think we're too far gone past the line of reason these days that it would make a difference.
