PRODUCTIVITY creates wealth. NOT STUFF.
Productivity implies production, which is making or collecting "stuff". Stuff can be traded for other stuff, like gold for food, clothing, etc. Wealth can be defined as having more than you need to obtain the stuff you need.
Yes. Helps to pin this down. Wealth should not be confused with a large quantity of something. Wealth is rather a transformative power of resources to answer to our needs. I found this snippet from Hilaire Belloc in
The Servile State.
Wealth is a function of what is considered a human need. For a radical example (which doesn't answer to physical needs) I am considered wealthy because I have been adopted into an inheritance through the transformative love of Jesus Christ.
As a side note, it is interesting that Maslow's hierarchy of needs had to be revised the hierarchy of needs gets upset when they are sacrificed for a perceived higher need.
