"Capitalism makes people unequally rich, but I would much rather grow our pie bigger and faster and better adjust the slices than redivide a shrinking one".

Exactly.    The idea is best recognized as 'income distribution'.   The pie is oversimplified, but for most people, that's about the end of their analysis or interest.  Which is fine, people are busy.  

Did anyone read the article that we don't have available on page 3 of the front section, "Updating GOP economics?"    I'd really like to have a conversation on that one.
