Everything about you is public, whether you like it or not. Until legal rights to own your own data exist it will be freely bought and sold to the highest/lowest bidder. It isn't how things should be, but it is how they are for now.
You should specify "in the US". In other parts of the world there are a few restraints (e.g. Germany).
Agreed it is like the wild west in regards to personal information these days in the US. Not so much innovation on the societal/political level preventing organizations and individuals from using data against you.
