Well, you asked why people are worse off, so I set it out. I’m sorry you don’t like the facts!
As for inflation, while government doesn’t control it it can cause it. As indeed it has.
And I think you misunderstand how interest rate setting works…the key driver is not the level of debt, unless there is concern that the borrower can’t pay it back. The Bank of England sets the base rate, to hits its target which is inflation. The inflationary actions in the last budget delayed possible cuts in interest rates, costing anyone with borrowings more. Though, ironically, benefitting the better off with savings :)
The level of debt can impact bond rates if the market loses confidence in the UK’s ability to meet its obligations s. Pre the Labour budget markets were, bar the blip caused by that madwoman Truss, confident that the UK would meet its obligations. But bond yields have been steadily rising since this government came into power because global confidence in the UK has been declining.
And, overall, the level of disposable income per household has fallen, with the poorest falling the most, since the governments last budget. So people are already worse off because of this government, and that is only going to get worse.
