I think their family has and is growing at considerable expense to the tax payer. They are certainly not meeting the costs independently, as would be appropriate. There is nothing to show why they cannot work.
I didn't infer anything about rent and tenants. Just the clear point that if a tenant finds somewhere to live which is less expensive, under the welfare reforms being proposed, they would benefit from the move. So would the 29 million who are carrying the cost for them.
