One could of course argue that Richard Wolff's sober analysis of the House of Cards economy, equally applies to the UK and the rest of the western world. We've been following the wrong economic dogmas for half a century and now more than enough people no longer support them and want to try something else. This is a profound problem for the system. Too many peoople are questioning too much. This means the political system is no longer as stabil as it once was, hence the rise of Trump, who rode into the White House on this wave of disatisfaction. That the 'left' hasn't capialised on this mood, is a tragedy.
I think Wolff is way to positive and optimistic about the new, young people on the Democratic side, chaging things. The historical precedent he refers to, FDR, was another world completely and FDR's policies happened after a tremendous economic crash that almost brought capitalism down with it. Today there's no real 'left' to speak of and no one like FDR around either.
