//If people don't do home improvements there is less work available//
Yes, thats a reason why there doing it... to reduce demand and spending. Yes it might lead to some job losses or reduced income for some trades but it will reduce demand and inflation. Its a blunt instrument yes and affects some more than others (eg pensioners with savings arent hit) but its been the weapon of choice as TTT say's for the bank of england which is seperate from goverment control and is tasked with reducing inflation.
All country's have inflation close to ours and use interest rates.... it takes time.
I share your reservations though- they should look at big picture. Theres a risk yes of inflation coming down but then a recession, so goverment needs to keep an eye on the whole picture.
As you say we're not economists
