Just a note: you _have_ to "tax the rich". Nobody else has enough money to pay the bills!
The question isn't whether to "tax the rich" or not - it's "How should we tax the rich" and How much should we tax the rich?" that we need to answer.
Meanwhile the correct answers are:
- Bring back heavy estate ("death") taxes to prevent wealth from being passed from generation to generation,
- Create heavy wealth taxes so that persons who are merely lucky don't monopolize the wealth.
Both the above should be done b/c goverment needs the money. Of course the other thing we need to decide is how much should the government spend, but that seems to have no limit these days.
