"Liz Truss is not listening to the IFS."

Other economists are available though you would not guess that after listening to the BBC. At times it seems like Paul Johnson is a BBC employee. Next thing you know, people will be saying he is paid too much, it is a waste of the licence fee, blah blah blah.

"Liz Truss is not listening to the big noises who used to work for Cuadrilla,"

Hard to know who she is listening to on this matter. Maybe the current big noises at Cuadrilla and their investors. But then she says "I’m clear we’ll go ahead with fracking in areas where there’s local support." Local support? Unlikely to receive that from many of her party supporters.
I think it will be a long, long while before we see any output as a result of fracking.

"Along with her new energy price cap and the tax cuts, both of which are designed to benefit mainly the better off"

Well yes the tax cuts will benefit the rich and so will the energy price cap. I don't see the sense in the tax cuts myself. The energy price cap is another matter. Those with bigger properties (and more than one property] will benefit more than the average person. I think capping the price at source is the least worse solution. Means testing leads to people missing out even when they need the help. There is also the costs involved in working out who should get the help.

There are not any easy solutions to the problems we are facing now. The costs involved in trying to solve the problems is going to have a long term effect on future governments, whichever party is in charge.
