I place very little value in the tory record of low employment, for a couple of reasons. First, the employment figures don't take into account the quality of the employment. As I mentioned, the majority of people on benefits are in work, so whilst they are considered employed, you could argue they are not 'employed enough'. Second, the tory party have done some very sneaky things with the numbers regarding employment. If you are on job seekers, you are considered 'looking for employment' so are not counted in the unemployment figures, yet you are not employed. It's bullshit.
As for Labour's policies, I have no doubt they are well meaning, but I've seen you laughing about this idea of McDonnell's 32 hour work week for everyone and I'm in full agreement. What he's done is read about the incoming wave of AI, and applied it to the full economy, which is fucking ridiculous. Yes, there are some sectors where there's evidence a 32 hour week will increase performance, but the key word is 'some'. Significant areas of the economy, especially the public sector (see teachers, the dibble, the military etc) need simple man hours put in to complete the jobs and reducing the hours on the same pay would be a fucking mess. McDonnell seems to read a lot of the same economist literature I read (as I've heard him quoting the same people I'm fond of, think Piketty, Stiglitz, Mazuccato etc) whilst simultaneously completely missing the point of what they are discussing. When Corybn was first going for Labour leader, McDonnell was on some program waving a copy of Atkinson's Inequality, What Can Be Done around. 'Fucking brilliant' thought me, because the book is fucking brilliant. The book contains a number of specific policy suggestions that would help reduce inequality. The number he has suggested as policy is the same as the number of Premier League trophies Liverpool has won.
