Not sure what the video is supposed to convey. There have been always beeb slums and some abandoned neighborhoods in the US for the past century at least. Are you somehow saying that those 8 blocks covered by that video are somehow the specific fault of one politician or president in particular?
Dude, click on that channel after you watch the video. There are hundreds more videos covering not blocks, but hundreds of miles that look like this. You can ride off the freeway through all those Red States for literally thousands of highway miles just looking at rural poverty along every mile.
The majority of the population in the USA lives in an area that looks like they are part of a nation that lost every war since the early 1940's. Look at Tokyo after the firebombing and look at Tokyo now. Look at Dresden in 1945 and look at Dresden today.
Who won the wars?
