I respect the NHS workers hugely and what they have done in this pandemic. However, a lot of the private sector have seen a drop in their real earnings since the financial crisis of the past decade. I know plenty who had pay cuts, had their pay frozen or simply lost their jobs.
The country is in a financial hole, unfortunately low to middle earners will be the ones that bear the brunt. If the economy booms after Covid is under control hopefully better pay for NHS and other key workers will filter through.
