Maybe "managerial" is a better criteria than "white collar" ? US culture has long preached that you are a stupid sucker if you perform direct work. The common sense recommendation for being successful is to seek out a meta position - directing poorly paid less skilled/educated/powerful people under yourself, and taking some of their production for yourself.

With information technology as the substrate, the meta-managerial class has continued to grow in size as ever more meta-managerial layers have been created (real world software bloat), allowing this type of success to be seen as a viable path for all.*

The meta-managerial positions and the upper class had a symbiotic relationship, with the upper class needing the meta-bureaucracy to keep everyone in line - some human-simulating-a-computer has to answer the phone to deny you health care. But LLMs simulating humans-simulating-computers would seem to be a direct replacement for many of these meta positions.
