I don’t know how you’re defining “rich” but the wealthiest folks I know all go to work physically. They get in their cars, or in one case on their bike, and commute to work like everyone else.

Concentrating on the very wealthiest is perhaps unhelpful, as there are very few of them, so they’re kinda irrelevant for planning purposes. Most well-off people I know commute to work on the train or bus; the city center offices where well-off people tend to work in Dublin are not generally exactly well-provided with parking, if they have it at all, and the traffic is pretty horrible. The office of the tech multinational I work in has 700 people, and capacity for more, and, I think, about 30 parking spaces.

Being on the DART (a not-quite-metro; trains carrying a thousand people every ten minutes per direction) or Luas (a high-capacity tram system) lines tends to lead to homes being considerably more expensive than those which only have bus access.

Dublin used to have a synthetic ‘posh’ accent that was often referred to as DART-speak, because it was common in the upper-middle-class suburbs along the southern section of the DART line. Public transport can be posh, or at least seen as such.

The wealthiest people I know are philanthropist that spend their day on zoon meetings to decide who get the grant. A couple of time a week someone arrange a visit for them to check on "things are going" on the trenches.

They also spend a lot of time on the phone strategizing with other folks like them. --

But that's not a contest!I'm sure your rich people are richer than my rich people. --

If we were looking at a formal definition, my naive approach would be to use the median income, add the revenue of assets, and add a 20% to that ?

I'm sure the field of sociology could help be more formal here. --

Here I was talking specifically about French folks, where access to remote work and living in the inner city are strongly correlated with higher income.
