Maybe that's a reasonable definition of white vs blue collar worker?
If you have enough excess income that you can build wealth in assets/investments until you become financially independent and no longer dependent on selling your labour, you're white collar.
If you don't, so you're condemned to work forever (apart from state support), you're blue collar.
