"We are going back to the good old tory days of high interest rates as the Tories do not know anything different! Yes I remember 15% interest rates and people losing their homes - decent hardworking people."
Rich people can manage the high inflation, which is an inevitable consequence of keeping interest rates too low for too long. They can buy index linked gilts, equities or even invest abroad. Inflation is a tax on the poor, not the rich. The labour policy was allowing uncontrolled asset bubbles with stupidly low interest rates.
"Thing is, I started when they were 15%, so I think 5% or even 8% is low"
I think you are looking at too shorter period of history. The average in the long cycle is around 3% I think, certainly somewhere between 2 and 5. For the BOE to hit its inflation target of 2%, the average interest rate should be (something like) inflation plus long term growth, or close to 4%.
The scandal for most solid mortgage payers with decent equity in their property is not the base rate, it is the current spread between the base and mortgage rate in a supposedly competitive market.
