The gulf between well paid white collar workers and regular people is so massive which is "closer" depends mostly on which billionaire you're measuring.
That doesn't pass the smell test. Outside the inflated prices paid by Zuckerberg the houses were worth around $4 million, which likely would be around be most their main net worth (let's say it is 5 million). The median net worth in the US is $200k so let's call the the cut off for "regular person" (by that definition >95% of people on HN would not be regular). So the gap from the millionaires here to "regular people" is a factor of 25, in contrast the factor to the smallest billionaire is 200, so no what you say is simply false.
