On the other end of the spectrum, 50-70% of US families were living paycheck to paycheck even before covid, so I'd be moderately surprised if the top 25% could afford whatever they wanted at the supermarket.
> The minimum net worth of the top 1% was roughly $10.4 million, according to Forbes. The top 10%, on the other hand, has a net worth of about $1.2 million.

Obviously. But if the figure is exclusive of their primary residence their return on investments isn't especially impressive-- e.g. it's sub index fund rates even assuming they have no other income than gains. :)
I wouldn't expect 'given' year effects to be relevant, as it's averaging over a large number of people. Taxable is a better argument, since as you reach the highest marginal tax rates there is a lot of reasons to find ways to indefinitely defer paying taxes (e.g. die with it and pass it with stepped up cost basis).
Being able to buy whatever you want at the super market is probably a top 25% of the US perspective if not more.
