David Cameron has gone to that old faithful, tried and tested policy of 'benefit reform'. More affluent voters love this to be dredged up every now and again as it appeals to their prejudices. Since those sort of constituents have no experience or any idea about being on benefits, it is much more of a concept to them. So if you put more people into training then an avalanche of new jobs will appear out of nowhere and suddenly the unemployment situation will be solved. These jobs are just waiting to be filled. I might be way off and I certainly don't hold a PHD in economics but if you want to decrease unemployment wouldn't you better off trying to create more jobs? Politicians know that re-training will do very little for the short term. But it certainly makes the job stats look better.
