And? Why would that stop them from getting this information and matching it? Are you saying because this information isn't available all over the world they wouldn't collect it it in the U.S.? The U.S. is the biggest consumer market in the world.
What do you think they could achieve (monetarily) having a personal history attached to a social account? I can tell you the first thing I'd do is determine your influence. I could take your addresses/family addresses and reasonably determine what kind of spending power you have based upon cross referencing your address with tax information. On top of that I don't have to necessarily know about you in another country. I can simply define the influence of an individual here and you may end up in their circle of influence. Imagine a person that's been voted as highly influential in said system and they communicate with you on a regular basis. From that I could infer that you are also potentially influential.
Other countries have similar systems. The information may not be as freely available but it's there. It just needs to be harvested.
For example, one of the biggest sources of relative information is obituaries. Something that is freely printed all over the place.
