New cars are status symbols or toys. I never understood how people could trade a human's full time salary for a car. People take old cars to work every day for a small fraction of the cost.
American lifestyles have inflated much more than the price of comparable goods. Average home size is way up over time, people prepare less of their own food, people buy fancy big cars with lots of horsepower and unnecessary capability.
I would complain about iphones and big TVs but in reality- the only things relevant to most of our budgets are our insistence to compete for the hottest real estate and new cars
Conspicuous consumption of goods is a interesting argument and probably worth talking about. But my point was scale and inflation.
It's not that simple. If nobody bought new cars, where would the used cars come from? :D
And their prices would go comparatively up.
So basically, they are just like everything else that you can get cheaper (which is, really, everything). Eg. you can get a comparable laptop for 1/2 the price most likely (maybe not with new M1 macs, but in a few years). Or the phone.
Realistically though back when being a millionaire meant 'retire immediately' things were much cheaper. You could get a car for 3-4k. Now a similar car would be 30-40k. You could say 'oh but that car is so much better'. That is true, but this 10x is mostly true across most goods I have found. I think many do not realize what a number inflation did on everyone in the late 70s and very early 80s. So many of these 'sayings' are still around but their numbers off by a factor of 10.
