Perhaps they will fall out of the limelight and have to get honest jobs that don't depend on their kids. Plus maybe folks will see that there's other stuff going on in the world, or turn off the television all together!

Kate was a control freak that yipped anytime anyone including Jon stepped out of line. Jon was an idiot and a scumbag to cheat though too, being he is in the public eye all the press of his infidelity will be forever online for his children to hear about.
