Having flicked through a few spots in the video, and being British, my conclusion is this:
Britain has got some major problems, many of which there is a lack of political will to fix, to the point that I could identify the general subject of many sections of this video just by the title on the timestamps. But the video is still pretty rubbish and overly sensationalised, with some of the opinions presented (smoking bans being bad, switching to an American style insurance-based healthcare being a good idea) are just straight up idiotic.
I would still rather live here than America though. Although Britain has been badly mismanaged by the Conservatives over the last 14 years, it is less polarised than the US, and the electorate as a whole are broadly tolerant and compassionate people who have very little tolerance of or respect for culture wars. The Conservatives insisting on trying to make this election about culture wars is a contributing factor into why their poll ratings are getting worse.
