No, Covid and more specifically furlough and then the cost of living crisis caused by Covid and then the Ukraine war have caused far more economic damage than Brexit IMO. Here’s some ideas:
Stop free prescriptions at the age of 60 and bring it in line with retirement age.
Charge at least £10 for a GP appointment.
Get rid of all DEI positions in the public sector.
Cut back where possible all non essential management roles in the NHS. Streeting is already doing this so fair play to him.
I’d like to see a complete overhaul and simplification of the tax system but I very much doubt it will happen in my lifetime
