I think most people would argue that labour would have supported the NHS prior to this, so better wages, etc. I don't think this would really help people leave the profession, we still have a massive shortage of nurses and I don't think chucking a few more quid will make people flock to the profession. Neither party can force people to work in the profession, I think it takes a specific kind of person to be a nurse or dr and I don't think it's always wage related (although it does help!)
In terms of actual cv I don't think labour would have done much different, just like the torris can't magic 10,000 ventilators out of thin air, labour wouldn't have managed it either. Same goes for PPE, I don't think it's tories not WANTiNG to provide it, it's a case of getting your hands on stuff. Companies won't normally have thousands of spare stock lying around, it's made based on need, and they would have kept production at the level people need, ramping production up takes time.
Lockdown wise I don't know if labour would have acted quicker?, possibly not. Would this have made a difference to death rates? Probably not. Sadly people are going to die and their isn't much the Labour Party could have done to prevent it. If we had gone into lock down too early would we have seen a sharp rise in cases once lock down has ended?
I think the tories have done remarkably well in a completely unprecedented situation. One I sincerely hope we never have to pay encounter again. You are always going to find people will loose out. Lots of self employed people saying that they don't get anything because of X Y Z,as harsh as it sounds the government are trying. They are spending billions? To keep people with a roof over their heads. But hey, I'm sure some armchair critic will be along shortly to tell us all how it should have been done properly.
