I love the way that supporters of the left (and, to be fair, the right too) seek to claim credit for all that is good.
The National Health Service was created off the back of the Beveridge Report, which was written by a Liberal. Whilst a Labour government created the NHS, it has been continued by the numerous Conservative governments since 1948.
The first steps to a welfare state were taken by Winston Churchil (a Liberal at the time) and David Lloyd George in the form of the National Insurance Act 1911.
The system of compulsory and state provided education was introduced and driven by Liberal governments. As for tuition fees, let's not forget that they were introduced by Labour in 1998, primarily to pay for the expansion of higher education such as to open up opportunities for more people to take that route.
It was a Conservative government that promoted home ownership for everyone with it's right to buy scheme.
I'm sure that we are all grateful for the part that the unions have played to improve conditions for the working man, but it would be wrong to suggest that they have been a universal force for good. The 'closed shop' was little more than a legalised protection racket in which you had to pay your subs in order to keep your job. The mass picketing and violence that marred indutsrial disputes of the 60s, 70s and 80s were examples of an attempt to intimidate working people who exercised their right not to participate in strikes that were often called off the back of dubious 'show of hands' votes in mass meetings.
Returning to the subject of the OP: A vote for Labour is a vote for Diane Abbott to be put in charge of policing and the security services. All those Labour supporters on here who have admitted that she is a liability or similar should reflect upon that.
