I'm relieved that Kwasi Kwarteng was fired as Chancellor

This doesn't solve Britain's problems but it helps. It proves that the Liz Truss ultra-rightwing agenda is already dead in the water. She has now been forced to u-turn on most of her tax-cut agenda. This means its less likely that we will see further savage cuts in public services or that those cuts will not be as bad.

It also means that Truss is now a lame-duck prime minister. Everyone knows that she was professionally and ideologically very close to Kwarteng and firing him shows a big loss of authority and credibility because it was forced on her. The country still has massive problems and the Conservatives have no valid solutions but at least there is some limit on how bad things will get/
