They have more now but only because Facebook gathered all of that, by themselves there's no way they could have the same kind of precision Facebook had.
There's no government program which records your position in real time, your interests, all the messages sent to your friends, the list of your friends, their occupation and where they are in real time, the news you read, all the information you are looking for... All of that in real time with an accuracy similar to Facebook (and aggregated as well, people often forget that most government files are not as neatly organised as Facebook...) . I could go on forever on the data Facebook has, no government program gathered as much as this, it's not even close. Not even the Soviet Union managed to get that much data on their citizens.
