Single Females --> the new valuable commodity

Many of us have encountered the type of management that comprises of Single Females. This i feel is the next most valuable commodity. Why so? well..
1) Single career women tend not to have a lot of social wants/needs as compared to bachelor men (i.e. partying, pubbing, picking up chicks etc) so in essence their lives become family + work
2) women in general tend to be more family oriented thus after work usually they will head home to be with their family thus the lack of need for social wants in 1) above
3) they are usually more detail oriented and in terms of management of projects etc this is a good plus
4) compared to married women, they have no need for maternity leave
5) some are of the mindset that they have no need for men and romantic relationships thus again minimizes the reasons to leave work early and supports 1)

How did they come about?
well some of them have been through alot of disappointing romance thus have ressolved to the "i don't need this crap" view of romance and relationships. Others have not been able to find a man that can swallow their ego and be able to deal with someone who might be higher up the corporate ladder. Others started off working hard and never found the time to find their other halves. And when they reach a certain age, the interest just drops off and the engine never got kicked started again.

If you compare it to men realistically they do hold more value and thus more power now than before and this is a rather interesting trend don't you think so?
