A classic case is when you observe teenager targeted status signalling trends. This can be as low value as an expensive shirt, ie shirts branded ‘supreme’ costing $300 which isn’t worth signalling to anyone who pays rent or a mortgage. But to a teenager? Wow man $300! such status!!! On the flip side if we see someone above teenager age wearing such teenager targeted status symbols we reasonably subconsciously assume they live with their parents and have very little income.
This continues up the wealth chain forever. Status symbols are invariably a way to see just how little people actually have because the person wearing the status symbol clearly believes the value of what they are flaunting is impressive.
Status symbols aren’t a signal of how much money you have so much as signal of what you believe to be an incredible amount of wealth to flaunt.
half a million for a car sounds absurd to me, but it's 0.5% of $100M. Compare that to $50k car on a ~$200k median net-worth US household.
If you're comfortably middle class and in a demographic recognized to "deserve" to be middle class, then you can afford to be oblivious to a whole lot of class signaling. You aren't striving to reach a higher station, and you aren't likely to get demoted out of your current one, so you can mostly ignore it.
People that are lower-class and trying to move up, or in demographic categories that are often shunned access to higher social classes don't have that luxury and are incentivized to be savvy to this kind of stuff.
This is one of the kinds of things that people talk about when they talk about "privilege". It's not that you should feel bad because you don't have to worry about this stuff. It's just an acknowledgement that some people have the privilege of not having to worry about this stuff because they were born into a level of class security that others lack.
You can have that heavy weight while living on the suburbs or even the ghetto too. The objects are prices mostly change with the wealth level, not the game.
