Finally, someone came at least close to figuring out the video's point.
Everybody understands the video is poking fun at the "hypocrisy" of the "liberals" who complain about capitalism while benefitting from the progress, the technological achievements and the wealth that it has given them.
Just because someone disagrees with the conclusions of the videos, doesn't mean they don't understand that it's trying to make that point.
Then why are you still misunderstanding it?
Up until like the very end when it takes a couple pot shots, it's pretty much focused on what is a common complaint: That the working class is not keeping up while showing that the conditions are constantly improving. People don't see how their lives are improving at such a rapid rate.
That conclusion is basically correct. I'm sure you want to add some nuance that it could be better still, but the basic point is solid. Things are getting better and they always have been getting better. The feeling of being "left behind", which is not necessarily a liberal idea, in fact such populism is a major factor in the Trump coalition, is, as a whole, incorrect.
