I think this is entirely reasonable.
People should no longer be allowed to choose to have anything deducted at source, because they are so stupid that they obviously don't mean it.
We need to make sure they know exactly what they are paying in tax, pensions, childcare vouchers, charity donations etc every month by making them do it manually.
And if Unions, which are organisations people choose to belong to shouldn't be able to deduct at source, no way should the state have access to people's pay cheques.
We should ban direct debits too - so open to abuse.
Let's go back to using chequebooks. It's the only way we can be sure people intend to pay for the things they are paying for.
