You only really need to watch the first five minutes of it to the the basic gist of the video; but the premise is that the majority of the poverty & political instability in the (First) World is down to the lack of available & actually useable housing stock. The main problem with it however, is that the author is a 🌐-Head who unironically believes in the "Free World", and fundamentally does not understand that everything that what they want to happen won't happen because the policies that he hates benefit the people who get to make the decisions under Capitalism.
