These aristocrats do not have any political power, but they have considerable social and economic privileges. Many of these families still own considerable land and along with it, tax advantages and certain rights that are attached to the land. Within society, they enjoy considerable deference. If they want something, they frequently get it. The have very important connections, an elite education, and they can use their title to find the right job, or the right investment opportunities. They can fall into things that you will never know about. Their titles no longer come with legal privileges, but those titles still count, in Europe these people still punch about their weight class.
