> share of the pie

Using words like that imprisons one into a certain perspective. Wealth creation is not "getting a share of the pie". Wealth is not an apple pie you slice up for your guests.

If Picketty uses words like pie, share, transfer, concentration, etc., then his book is about as valueless as Das Kapital.

For what it's worth they are my words not Picekty's.

It does not matter what it's called. The buck stops at the basket of goods and services I can buy. As long as this basket of goods and services is evaluated in inflation adjusted terms, it is pertinent to the discussion we are having.
