You don't need to take it to the congress; just stop using the services of a company whose practices you don't agree with. If more people would do this, maybe the company will get the message and change its practices.
This information is too valuable to dissuade companies from collecting and using it. You can't do much as an user if everyone is doing it. In many situations you might not even know that you're being tracked, there already technologies that track you in public places.
IMO this is something that should be regulated.
