It’s not a race to the bottom.
Someone on a higher salary is likely to struggle precisely because they’ve never had to.
When you’re on a lower income you are more likely to watch what you’re spending, and so when we end up in a situation like now they have already learned to live on less.
Someone on a larger income may either have higher outgoings, such as a bigger mortgage, bigger car etc, but equally they have likely not had to watch what they’ve been spending so closely and so when they have to they find themselves struggling as they’re living to their means and it’s not as easy to cut back.
So a person living in a 4 bed house is likely to incur higher energy costs than someone living in a 3 bed or a flat.
Someone living in a 4 bed is going to have a bigger mortgage, and no, it really isn’t as straightforward to just sell the house and move to a smaller one. After all, who are they going to sell it to if all these people living in big houses need to sell them, and that’s before you get to conveyencing costs, estate agents fees, stamp duty, the average cost of moving house is £15000.
Equally second hand cars have little value so you’re telling someone to spend more money on a new car…
