It's the easiest thing in the world for any politician to say "This is what we would have done, and we were saying to do it years ago … " but the simple fact is, if Labour was in power, they may (hope to God!) be doing the same, but they would be doing it for the same reasons as the Conservatives - namely, it is what has to be done but …
If we were not in this position, and Labour was in power, it's highly unlikely that they would have poured in all these resources, because the world economy would not have allowed them to.
The money comes because of the crisis, nothing more.
