 We would never let a real-life babysitter introduce our kids to racists, conspiracy theorists, or women haters. We wouldn't let a babysitter show our children violence or give them drugs. But social media companies do this every day, making billions of dollars by feeding our kids content that damages their mental health and self-esteem. So before we hand our kids off to the digital babysitter, just remember that social media is addictive and profitable by design.
