The white-collar types are the ones that start small businesses and employ blue-collar types. The blue-collar folks were told to improve their skills and move into the white-collar class long ago. Now those former blue-collar types are finding themselves in the same situation with their new white-collar brethren. Huh, your above italicized passage is contradictory. In your first sentence you basically state that blue-collar types can't become white collar types and yet as you go on you are saying that former blue collar types had become white collar types.
You are spinning in circles, IMO.
I never implied blue-collar workers couldn't start their own businesses. It's called upward mobility, the ability to move to a different skill level and increase personal wealth. No circles here.
This also doesn't preclude white-collar types from becoming blue-collar types if they lose their job and cannot find another. This is called downward mobility.
