If a group gets wealthier while everyone else gets poorer, then the first group has extracted that wealth from the second group. The thing about taxes is that they act on groups and equalize things. They are what makes (or, should make) this ficticious person of your pay for the construction of a road that he will never step on, or for a school that his children will never use. The wealthier they are, the more they have extracted. Thus the more they should be taxed. It is really not that difficult.
