In a meandering answer to a question about racial inequality in schools, Biden said one way to help educate kids is to “make sure the record player is on at night.”

Biden said social workers should be brought into homes to help parents “deal with how to raise their children.” He then said it’s not that some parents don’t want to help, they just don’t know what to do.

“Play the radio, make sure the television, excuse me, make sure you have a record player on at night,” Biden said, “make sure that kids hear words, a kid coming from a very poor school, or a very poor background, will hear four million fewer words spoken by the time they get there.”

Castro, who spoke next, said, “Well, that’s quite a lot.”
