Pastor Mark Driscoll has written a piece in the Seattle Times that is worthy of a read.

"The problem with both these theologies is that they make money the
issue. The real issue is not money but righteousness. There are not two
kinds of people — rich and poor — but four kinds of people:
the righteous rich, the unrighteous rich, the righteous poor and the
unrighteous poor."

"When the issue of money is framed as rich and poor instead of righteous
and unrighteous, we are allowing politics and economics rather than
spiritual wisdom to dominate our thinking."

Covetousness is desiring something so much that you lose your
contentment in God. Or: losing your contentment in God so that you
start to seek it elsewhere.    - John Piper
