Re: So when will the politicians learn?
"May moved left (energy price cap FFS) to capture some of the middle. In the end, she just validated some of Corbyn's positions."
Indeed, but bear in mind that she started off in her first speech by very firmly parking tanks on Labour's lawn in terms of spoken policy - which had people hoping that the conservatives might have actually seen the error of their ways, but then U-turned on that and went full blown "nasty party" within weeks.
When that was shown to be unhelpful, she may have moved left again (and Corbyn's policies aren't that extreme - the conservatives used many of them 60 years ago), but having rattled her core "grey" voters with the level of proposed nastiness(*), I'm pretty sure that all subsequent U-turns were taken with a large dose of salt by them and middle-ground electoral slugs, especially when the Conservatives were selling uncosted policies which would drive 80-90% of the population into poverty whilst decrying Labour's relatively well costed out plans as unworkable - and responding to anyone in the media pointing it out by simply attempting to shout them down.
(*) I'm fully and painfully aware that pensions policy over the last 50 years has been a £100 trillion ponzi scam(**) and that my retirement age will be 75 if I'm lucky, but I was aware of that back in the early 1980s and have been expecting it since I was 18 - most Boomers and early GenXers simply believed what they were told instead of crunching numbers on birthrates.
That said, the level of cutbacks on elderly healthcare and proposed effective financial penalties rank pretty high on the Grinch scale. GenX and GenY are likely to suffer retirement of 75 or beyond (if they can actually afford to retire). Millenials may see it reduce again, but it's unlikely to ever go below 70, or be compulsary (which was done to ensure Boomers had guaranteed jobs to walk into. The window on that was closed even before GenX entered the workforce)
(**) right across USA/UK/AU/NZ and many other "developed countries" - where the population was encouraged to spend more and save less. The oncoming trainwreck was forseeable from the mid-late 1970s and makes Bernie Madoff's antics look like child's play. Boomer grandchildren and great grandchildren are going to be served with a very large bill and there's a risk they may choose not to pay it.
