Monday March 25: what does it mean?

Greetings children!

We've been talking for some time about industrial development, growing economies and differences in income between people and nations. Today, I would like you to begin by helping to define the following words. Words are used so often by so many people, often without any thought to what they actually mean.

Tell me, what do these words mean? (Not less than four complete sentences to explain each one. And please give specific examples of what you mean, either from your own personal experience, study of history, your extensive reading of the Wall Street Journal, etc etc) 

money  --

wealth --

resource --

raw materials --

property --

patent --

copyright --

economic development --

Please send your results to me in an email, with your name and the phrase "what does it mean?" in the subject line

cheers,
Mr. L
