How much of that is just a cost thing? Is hiring people to do home maintenance inexpensive and easily available where you are? That's usually not the case in American cities.
Some of it is cost. And almost everyone knows a handyman or somebody in the neighbourhood who is an electrician, concrete guy, tile guy, &c. But part of it is cultural. It's considered a form of virtue signalling to have a bunch of servants or workers on your property. Most middle class people also have maids, nannies, drivers, and such.
