I've just been reading an article of the Green Party website called 'We need a Green New Deal, not a Brown New Deal' and I think I have an answer to one of the questions raised from it.
The article mentions the fact that investment in what it calls a 'real Green economic package' (what the party calls the 'Green New Deal') could generate hundreds of thousands of jobs and the tone of the article suggests that the Green party are puzzled by why the government doesn't appear to be doing much towards creating these new jobs.
Maybe I'm a cynic, but a big part of the 'New Labour' ideology appears to be to put as much business in the hands of private companies as possible and the focus of most private companies is to make as much profit as possible (not, alas, to provide a service to their customers these days!). Therefore the easiest way for a private company to maximize their profits is to keep their work force to an absolute minimum as wages make up a large part of any company's outgoings. So whilst the idea of the creation of hundreds of thousands of jobs in one respect is a very positive thing, what goes with that is hundreds of thousands of wages that need to be paid out and it is this that is likely to be unattractive to the current Government.
What can be done to try and change this very narrow minded and short term attitude, I don't know (a change to a Conservative government is not likely to change this kind of thinking within the UK political system), but I think this is the root problem with current government thinking.
