Yeah people that whine about the Fed needing to cut rates sooner than later really don't get the big picture. As this shows since 1980ish they have done a really good job keeping inflation and deflation in check. It's painful, but as we still see today people just want to spend spend spend and that's the cause of inflation. When supply chains dried up during covid if everyone would have simply only purchased what they needed vs what they wanted we would not have seen the inflation we did. At the same time more than half the working population got huge wage increases relative to what they were making (very little) and what did all those people do with that money, they of course spent it. Then there was the giveaway of our tax $ during covid to help prop up businesses. It all added up to what we see now. Everything is about supply and demand, want lower inflation spend less, but not too much less or you risk deflation. Since people can't grasp the concepts they use the interest rate for force people into less spending. Low interest rates are the carrot to spend more, high are the stick.
As for Millennials and Gen Z, when was the last time you saw one without a $1000 phone <2yrs old, a foo foo coffee, eating out or ordering delivery all the time, taking uber everywhere, etc... Their problem isn't the amount of money they make, it's their poor spending habits. Poor work habits of many compounds their problems, or will as it catches up to them.
Those that make <$30k/yr can't be expected to save anything, it's all ate up in mortgage or rent plus other monthly expenses regardless how well they budget.
Those making say $50k/yr might be able to save some, but to do so they would otherwise be living hand to mouth and on a very tight budget.
Those making more than say $80k/yr really have no excuse not to save, they could if they simply managed their money better.
I've been in all these groups over my lifetime, I still remember the first time I went to the market and didn't pay the slightest attention to what the bill would be. No trying to add up the cost as I shopped, then worrying I'd be short at the register and have to put something back. Best day ever.
