You must be mistaking Kaku for someone else... Kaku is concerned that dishonest people attempt to control masses using people like Tyson. He describes two different worlds yes, but rather one where a big government controls thought with propaganda and by manipulating science, vs one which does not attempt to do so. Kaku discusses implications of such manipulations and explorers parallels to history, while DeGrasse Tyson and Bill Nye are simply tools used to carry out those manipulations, for money. One has been driven to obscurity by the mainstream media, the other bathes in it's wealth.
