There are many people who are in a financial position to contribute more towards funding for the NHS and who would be happy to do so.
Making the contribution voluntary means that people can pay extra if they can afford to and reduce or stop the contribution if their financial situation changes.
If people know the money they are contributing is going directly to the NHS then I’m sure many would be happy to contribute.
