We usually hear the word "empowerment" in one of two contexts. Either someone is talking about one social group (race, gender, orientation, political party, religion etc...) needing to be empowered by society. Or someone is talking about a specific individual "finding empowerment". Of these two usages I prefer the second one but overall I think the word ought to be dropped from the language entirely. Before I go into the two usages though, let me talk about the word itself.
In the first usage (empowering a social group) I don't think the word can be used without contradicting the intentions of the person using it. Specifically, if I said that some group needs to be empowered that can only be because they currently lack power. It is possible that I would make the claim in a sort of off handed way claiming that some group or other really ought to have power, but that is unusual. Usually when the word gets used someone is talking more about taking power from another group (usually a majority of some sort) and giving it to another group. A sort of redistribution of power. Which is condescending. Really condescending. If I were to walk up to you and say "You know what you need? You need power, so lets take some from that guy over there and get it for you." You cannot really talk about empowering anyone without suggesting that a) they don't have enough power and b) they can't get it for themselves; someone else has to get it for them.
Not only is that insultingly condescending in a social context but it lacks a certain amount of historical viability. At the present I can't think of a single social group which currently has power which they did not either inherit, get from God, or get for themselves. People just don't do third party swaps on power.
In the second usage (empowering an individual) I have less of an issue with the use of the word but only because people almost never mean what it actually means when they use it. Properly understood, the phrase "You need empowerment." means something like "You don't have enough power, and you can't get it yourself so you need to find someone to get it for you". But in actual usage it generally just means "you need more power." Which may or may not be true in a given situation, but either way it is a case of misusing the language and potentially conveying an assumed superiority.
Of course there are times when it is quite appropriate to talk of empowering someone. Deputies are empowered, they don't have police power, they can't get it for themselves, it has to be given to them. Children are occasionally empowered by their parents who quite properly have more natural power (moral, physical and legal) and can, on occasion lend or give it to them. And God is omnipotent. So ultimately all power in existence is a result of divine empowerment, quite properly so.
The problem is when groups of naturally equal power (especially legal or moral power) start to talk about empowering one another. When this happens the relationship between the groups must be artificial and strained from the outset. One is the group with the power and however they feel about that (guilty, proud, justified, unjustified) they will see themselves as different both in capacity and quality from the other group (remember "empowerment" only happens when the receiver can't get the power for themselves).
Or am I wrong about this? These are just my reflections on why I dislike the word so much (my other thought was that I don't like it simply because power is almost always the wrong thing to focus on in any relationship) they may be way off base. Please let me know either way.
