Hmmm....
Sorry, I didn't read the article. Neither did I read the exchange between you and Tom.
You said "inflation is the path to riches" for the wealthy. The other side of that coin is that inflation is fought with higher interest rates. This will benefit those who you noted, are "living off their savings" because those savings will be earning more.
Higher mortgage rates will be a plus. Banks will be more profitable and tend to lend more freely in today’s environment. "Savings" will earn more. In my opinion for a robust economy interest rates should be around 9% with credit card rates being slightly higher depending on risk.
