Yes, price inflation measured by the CPI, which consists of a changing basket of goods from the lower end of the market, has been low.
Let's say a given widget costs $10 to produce, and look at what happens over 4 years. Say offshoring, cost optimization, and technological progress would allow it to be produced for $7. The Fed creates enough new money that the new price is $11. The Fed calls this "2.5% inflation", whereas the actual inflation has been 12%. The sticker price reflects the 2.5%, and the remaining 9.5% is reflected in the item being made cheaper, not supporting the local economy, and the gains of technological progress accruing to the central bank rather than being distributed throughout society.
At the larger level, this does not happen uniformly to every component of CPI. Instead, prices for things that can be bought with new money increase more. So manufactured goods still have relatively low price inflation, where things that the consumer can finance (housing, education, healthcare, vehicles) shoot through the roof.
Bringing this back to the original topic - since the median consumer's expenditure is expected to be ~fixed (slightly rising) for a basket of goods that are decreasing in quality, they're unable to afford the previous baseline quality that is now considered luxury. Rather than seeing a choice between buying what they know and saving money with a lower-quality item, they're given a choice between paying slightly more for the lower quality one or paying much more for the quality that they were used to.
