Despite the claims of Braverman (she's wrong by the way), I'm not sure you've truly grasped what 'people smuggling' actually entails. For the overwhelming majority, they end up as 'modern day slaves' paying back the fees for their passage and the promise of a better life. Most of them don't even have a change of clothes let alone a large bag stuffed full of readies.
It's quite ironic that those clamouring for the boats not to be stopped are likely the same people clamouring for the statues to be torn down, whilst not realising they are technically supporting the modern version of slavery. Stopping the boats is good as it will reduce the slavery and exploitation. Maybe if that was outlined, more people would accept it - but I appreciate that isn't the headline grabber in the run up to an election.
