What’s the difference between our forefathers owning slaves and enslaving our kids to smartphones?

I cringe while watching a tv interview with the liberal guy who was calling some of our most cherished forefathers scumbags because they owned slaves.
The Brainwashing of American Youth
Now I’m no fan of slavery, but I watch this knowing that American kids are being brainwashed by these same idea logs all the time. And by tenured educators no less!
But you have to wonder what future generations might call today’s garden variety parent since many of us have allowed our kids to be virtually owned by and enslaved to their digital devices.
I pray for the day when smartphones will be outlawed for minors, just like alcohol, tobacco, and gambling.
Maybe if we all rally now, posterity won’t view us with similar contempt.
