Measuring televisions through fiat only gives you a part of the story. Measure them and everything through #Bitcoin and you’ll see the full picture.

Television sets are the extreme example of what’s possible. I don’t see any other product where they let the price collapse like that. Do you?
Everything (save for artificial intervention) is getting cheaper, starting from commodities. This is true when measured with a constantly shrinking measuring stick in fiat.
Now couple with technological progress and you will see why the price of un/low regulated products keeps dropping. 
Why aren’t my Mac upgrades cheaper than before? Why aren’t iPhones getting cheaper? Why aren’t my cars getting cheaper? Like televisions.
All of the above: you are measuring in fiat (imagine measuring your nephew’s growth with a height measuring stick that changes its length materially in months).
Macs & iPhones: you are conflating luxury goods with cost of unit compute power.
Cars: regulations. See https://www.roadandtrack.com/reviews/a45752401/toyotas-10000-future-pickup-truck-is-basic-transportation-perfection/
Modern TV sets are data harvesting computers with big screens and producers make a lot of money selling the data they harvested from you. Some make lore money from selling your data than from the hardware itself, they decrease their profit margins on the hardware to sell more TVs to harvest more data which is more valuable.

👆🏼 this is key, and most people don’t understand it.
Just because prices are not going up it doesn’t mean you’re not getting robbed. Even if CPI was 0% that still doesn’t tell you much about how much PURCHASING POWER we could all be missing out because of monetary policy.
Saying oh well the Fed expanded the money supply by X amount but we didn’t see any inflation (or high inflation) as George Gammon would point out does not paint the whole picture.
Once ppl understand that prices should fall to the marginal cost of production over time, as you point out Jeff, then they will know they are being robbed even if prices stay flat
