We do not need a strong economy to pay for the NHS. We need a strong NHS as a pre-condition of a strong economy. Government spending always comes before tax revenues can flow in. Never more true than the moment we are in now.
@ster @RichardJMurphy health workers are people too! Like any others but the richest, paying them more means they spend more.
And actually it's not mutually exclusive - governments can invest in more than just a functioning health service.
