On the topic of inflation itself rather than the accuracy of inflation metrics -
Some interesting data points here.
Meat prices up 13.0%
Fuel up 43.6% (although this is arguably more due to geopolitics than it is inflation)
Used Cars and Trucks up 41.2%
Airline fare up 12.7%
Even something like rent being up 4.2% can have a major impact on people that live paycheck to paycheck.
An illustrated example:
A worker makes $2500/month and takes home $2000/mo after taxes in disposable income.
The worker's living expenses are $1800/mo. Giving them $200/mo in discretionary income. (Note the difference between disposable and discretionary - disposable is after taxes but before bills are paid, discretionary is after taxes AND bills are paid)
If prices go up even just 5% without the worker's wages increasing, then their living expenses increase to $1890/mo, and their discretionary income drops from $200/mo to $110/mo - that's a
55% drop in discretionary income.
With the current 8.6% inflation rate, said worker's
discretionary income drops by 77.4%
