I think the concept of necessary vs. luxury is a critical one, both because of the concerns
@ChpBstrd raises, and because redefining our own definition of "necessary" is the most effective way to manage our own expenses and make choices that increase our own happiness.
But I think it's short-sighted to characterize every spending that you deem to be "excess" as "status spending." Partly because that term implies a moral judgment that is off-putting to those it's directed at. But also because it's inaccurate, and if you create your investing view by assuming that all excessive spending is status-driven, you will reach incorrect conclusions in many cases.
I will give you a couple of examples from my own spendypants life. I am in the happy situation
@Ron Scott mentioned of being completely FI -- wealthy, even -- and thus really don't give even a minute fraction of a shit about what anyone else things. I actually adore living in a neighborhood that is well below what society says we can "afford," because I can fly beneath the radar. And yet I spend a metric shit-ton of money on stuff that in no way qualifies as a "need," because I wanted to:
Example 1: My DD's car. First, giving a kid a car in HS is complete and utterly unnecessary luxury. But, damn, it made my life way easier once she could get herself to her own activities, and we could afford it, so I gave her my old car and upgraded myself to my StupidCar. But then I went even further into the depths of excessive spending and traded that car in for a lightly-used Subaru. Why? Because it had active crash-avoidance features, and DD has ADHD, and it was worth it to me to pay maybe another $8K to improve the chance that she would either be able to avoid hurting herself or someone else as a result of a moment of stupidity, or at a minimum decrease the severity of the accident.
Example 2: I own several Coach purses. Totally don't need them; I mean, really, who needs a purse anyway if you buy clothes with pockets in them, right? So why? I mean it's a total status brand, right?* Well, they're really pretty and well-made and last for-freaking-ever,* and the company will repair any problems that come up. In fact, I actually hate that they're such a well-known status brand, and I refuse to buy the ones with all the logos all over them.
Example 3: Eating out. When Covid hit, our takeout/delivery spending went
way up. Not because we're lazy or can't cook or want to impress people with our fine dining. But because we knew a lot of local places were really, really hurting, whereas we both maintained our jobs and were largely unaffected, so we figured if we wanted them to stay in business, then we should use some of our good fortune to support the places we cared about.
I could go on practically forever, because really, everything is excess once you have a roof over your head, clothes on your back, and food on your table. But the drivers for each decision are different, and so will respond differently in different economic circumstances. Option 2 is pure luxury and would disappear in a heartbeat if needed; I already have purses and could easily just not buy any more (and in fact I haven't for a couple of years). Option 3 is more on the lines of charity, so while it would be cut back if I needed to, it would rank higher than the purses. And option 1 is driven by concerns for my family's safety and so is going to remain a high priority for spending under any circumstances -- I might defer buying a new car, but when I did, it would have those features.
*It's actually a very bougie status brand; truly wealthy show-offs would never be caught dead in something so mass-market.
*My mom has had a satchel she uses for work for probably 40 years, and I've had a similar one that I've used every day (when I was still commuting) for at least 20.
