Why don't you try it. Turn your electric off at the mains and sit in your house in the dark. No hot water no heating and no lighting virtually every night if you miss it so badly
Under the Tories now, with our current system, we see plenty of this happening. People forced to choose between a fiver on the stick (bunged with higher rates for some reason - yes those who can afford it least paying more) and food for the children. We see it everyday, everywhere. Under the Tories today.
We see rates for trains and utilities going up and up and up - when fuel is really at historic lows. Under the Tories.
Under the Tories we have many sneaky things like this that bugger the poor two ways to Christmas.
Under the Tories we have food banks now - while supermarkets poor bleach on their throw out food to keep hungry people from pulling it out of the bin. Under the Tories.
All these things are happening, not in the 70s, but right now.
Under the Tories.
