I don't know about Bloomberg in particular, but it now seems almost common wisdom among the elite that college isn't for everyone and now skills like programming aren't either.
While those words are true, what they mean in practice is that 'not for everyone' means 'not for the poor and working class' (poverty is a strong predictor of college eduction). I bet Bloomberg's kids go to college and he wouldn't doubt his non-technical buddies' ability to learn to code based on their job descriptions
What happened to the American Dream? Where is the land of opportunity, where anyone can succeed if they work hard enough? Apparently, Bloomberg et al believe that only the elite live in that land and that we should abandon that dream for the working class and poor. Why don't they just accept their places?
