We were thrust in to an interesting social experiment during our 3 year expat time in Dubai. People from all over the world seem to 'adjust' pretty quickly to having staff when it is the expected norm. We were pestered (and ostracized) for not taking on a nanny for our 2 children, as though our mirror to others was a bit too unpleasant, with the constant refrain 'but you are supposed to hire them, it provides them work'... Little mention of the fact they are underpaid and have to give you their passports, while also having a very unfair legal and social dynamic stacked against them. Yes, many staff choose 'freely' to come to the Middle East from India, Philippines, Indonesia etc. for this, but it's still repugnant to know better and still indulge - or maybe that's just a vestigial moral code.
I'm just writing all this because many people like to think they would 'hate' to have gardeners, maids, cooks, etc. but suddenly found them indispensable when the social and financial restrictions weren't there... We did have an easier time returning to the US. Others typically tried to continue with at least a nanny, but it became much tougher when you are the only one in your home country with one and you also have to pay them living wages, give them vacations, and allow them freedom to leave at any time.
I view the UHNW social cohort as being like a mini-Middle East... They all have staff and the pay is a relative pittance to what they could afford. The only thing that would keep most from having staff would be choice when surrounded by others and the expectations that it only makes sense to hire others to do certain tasks. I've heard a million times in our neighborhood that we should stop doing our yardcare because there are so many willing Mexicans desperate for the work, and having a chef only makes sense so that we can focus more on eating well and ourselves...
I'm honestly not sure why we have this 'Mustachian' bent while so many others with our situation (or in many cases, less NW) do not. It hasn't always served us well in terms of fitting in and moving up the social ladder. But it is what it is...
