Thomas Sowell is a walking encyclopedia.
But the point of this video, the example given (of which I suppose there are many) is that we in the United States should learn from the past and let go of grievances (from the past) as these can be found everywhere.
There are always those who benefit from creating division, and in this country, we know who these people are. We should not fall into their trap, although I fear it may be too late to avoid this.
The bottom line is that the Left is basically playing the role of the Czechs in Bohemia, and the only ones who benefit from this are the relatively few individuals at the top of the food chain, mainly the leaders who run our country and their cronies. Eventually, only they win while the rest of us are left with nothing, not even our freedom.
