MSNBC host Mika Brzezinski on Friday ripped a panel of male pundits on the Fox Business network who were upset on Wednesday by a report that said women were the primary source of income in 40 percent of U.S. households.

Fox News contributor Erick Erickson told host Lou Dobbs that the idea of female breadwinners went against nature. Fox News political analyst Juan Williams also lamented the "disintegration of marriage" and contributor Doug Schoen warned that "it could undermine our social order."

"That was like caveman central!" Brzezinski exclaimed on Friday. "What the heck was that?"

"The fact that this day and age, that we could have men talking that way is stunning," panelist Donny Deutsch agreed.

"We're in the middle of a generational divide," co-host Joe Scarborough explained sarcastically. "And, you know, Erick, my good friend -- and he's a good friend of mine -- Erick's 65 years old."

"But, no, we're in a transition here, Mika," Scarborough continued. "And for a lot of guys, it's difficult."

"I would try and counter their arguments and say the problems with our society or our social order or whatever else it was we're so concerned about was them, the cavemen," Brzezinski insisted. "They can't take it. They can't handle it."

"They're struggling through a tumultuous time," Scarborough snarked.
