I guess what he is trying to say is that some decisions on where to build highways was decided, at least in part, based on the demographics of where people lived.
But what are we supposed to do about it now? Spend hundreds of billions to tear them down? That money could actually do a lot of real good for real people. So I’d say their decision to waste all that money to blow up highways is equally racist. And, meanwhile, people living in those areas will lose access to highways and spend more time in traffic and breathing exhaust in the streets.
There was a Honeymooners episode on approximately this premise! Ralph and Norton were going to get rich owning a motel or something but tbe new freeway passed them by!
