Writer Jeff Jacoby does a great job describing the difference between the "Occupiers" and the "Tea Partiers" in this piece from Townhall.com - Occupiers, Tea Partiers, and the Tenth Commandment:
"Economic envy may cloak itself in rhetoric about 'inequality' or 'egalitarianism' or 'redistribution of wealth,' but its oldest name is covetousness. That is the sin enjoined by the last of the Ten Commandments: 'Thou shalt not covet thy neighbor's house; thou shalt not covet thy neighbor's wife, or his manservant, or his maidservant, or his ox, or his ass, or anything that is thy neighbor's.' ""
The Catholic version of the ten commandment may read slightly different, but the point is still valid.
As Jacoby points out, the Tea Partiers are motivated by self respect while the Occupiers are motivated by envy and covetousness.
No matter how much the Left may want to convince you otherwise, the groups are not similar.
