In America, tech giants know a lot about us. John Stossel says that's fine with him. He knows what information he's handing over and he does it voluntarily. But he says we should worry about becoming like China, where the government is starting to use online data to create 1984 in the real world.

China's government has announced that they'll assign a mandatory government "social credit score" to everyone in the country by 2020. It will be based largely on what you do online. Say something that gets censored, you lose points. Same if you watch porn, or are late in returning a rented bike, or buy lots of alcohol.

China's government boasts that the social credit system will "allow the trustworthy to roam everywhere under heaven while making it hard for the discredited to take a single step."
