No landlord bashing intended!
I assume most people put rent or mortgage at the top of their financial priority list. Housing benefit bill is ginormous, and for renters. You can't get HB to pay the mortgage on the house you live in. Ergo that vast chunk of cash is being paid as rent. I'm using "landlord" in a very general sense, to mean 'the recipient of the rent'.
Essential utilities are next on the priority list: gas, electric, water, internet (which is in practice if not yet in law a prerequisite of claiming benefits).
If a household pays the above and finds themselves with anything left over: great! They'll spend it on food, clothes, treats - keeping the money in circulation, paying VAT, providing custom for shops and small businesses. But if all they've got left over is a tenner a week, they're paying very little tax and providing very little custom. Which obviously has a knock on effect.
Where in earth was the landlord bashing in that?
