Sadly, the perception will always be that there aren't enough workers in tech, or that there aren't enough "good" techies, when that hasn't been the case for many many years now.

While a lot of people do leave tech for management or other careers, bootcamps still sell the dream to make money, and people always talk about how "learning to code is so important to society". There has been an effort in the last decade or so to flood the market with entry-level workers, that we're now in a situation where people are spending thousands on qualifications, only to find it near impossible to get the job - or finding that no one gives a fuck where you went to college and that you need to "LC or GTFO".
