What crack was the YTber on?
Income has only raised ~15% (on average), while inflation has been at 30%... meanwhile in the past century, money has lost 96% of its value...
Not sure how that translates at all into "stuff" being more affordable...
Durable goods have deflated compared to wages while health care, housing, and education soared. If you are given the job of spinning this (or take it upon yourself in a bid for access), focusing on the former to the exclusion of the latter is how you do it. "Think of the iPhones! Never mind that rent in a mid-rate city is 1 iPhone and 2 big screen TVs every month!"
What is the time period for you numbers?

I'm pretty sure "stuff" in this context is mostly manufactured goods, and those have fallen in absolute price. Examples abound in the tech sector: even adjusted for inflation, a MacBook Neo is the cheapest Mac ever released, and so on...
