What do the wealthy have now that will roll down to the rest of in the next 10 years?
I was car shopping this weekend and was blown away by the tech features that are available in even moderately priced cars. Adaptive cruise with lane assist, blind spot monitoring, backup cameras, navigation and even reverse automatic breaking. Even base models had quiet smooth rides.
When I bought my last new car 10 years ago, this was only the stuff of luxury brands. So that got me to thinking, what luxury commodities will become affordable in the next 10 years?
Trickledown wealth, yes, but the spirit of OPs question is “stuff”. “Stuff” does generally get cheaper over time.
I bought a 55” Plasma TV in 2008 for $2100. Last year I bout a 65” OLED for $1600. Much better picture, much thinner/lighter, much lower power consumption and heat generation.
Solar panels prices have, for the past several decades, been dropping like a rock while also becoming much highwer quality and higher efficiency. It's only now that they seem to have for the most part leveled off. Now the panels the cheapest part of a solar setup. Batteries, inverters, and charge controllers are the more expensive items.
