Haha that guy. He's got a relatively defensible argument of "It's possible to get rich." and implements it in the worst way, "The fact that 1% is equal to the bottom 50% is a great fact because of my overall argument!".
Maybe it never gets much traction because a talk show can't describe the argument in enough detail but the fact that social mobility is highest in socialist countries summarily defeats the primary argument against wealth redistribution of 'If you give someone something for free he'll never aspire to work for himself.'.
