The danger is in people believing the Constitution automatically fixes this. It is a disservice, because it demotivates people from taking action, when action and political efficacy are the only things that can fix this.
Originally, the 4th Amendment only restricts the *federal government*. It does not *automatically* affect anything else. In fact, constitutional amendments (including the Bill of Rights) don't automatically apply even to *state* governments. They must be *incorporated*. Most have, including the 4th, but most people don't realize some amendments such as the 5th Amendment have not: https://en.wikipedia.org/wiki/...
But even when rights are incorporated by state governments, the federal and state *governments* have nothing to do with *private companies*. Unless laws are passed that explicitly restrict behavior of private companies, they can collect and sell all the information about you that they want. That's the loophole of the rich and powerful: if government can't do it, companies can. Regular citizens didn't win guaranteed rights due to the Constitution, they simply reduced the total number of ways rights can be taken away. We must still fight for them. Always.
And I'm saying this as a (mostly) conservative. "Republican" and "Democrat" has nothing to do with republics or democracies anymore. If we want to fix our problems, we need to stop the petty party bickering and actually discuss the issues.
