But the live-in servants have been replaced by external servants. People who are expected to be working when at 11pm I decide I want to eat a bite of food, yet are paid below what it takes to raise their own family and are working 2 jobs at once to make ends meet.
The boundary between nobility and servitude is more blurry, and yes there are a lot more ways to rise out of servitude than 7 centuries ago, but I'm reminded that all the niceties I currently enjoy are still coming at a price for those working in the system that supplies them to me.
Having lived in Europe and in the US, I'm aware that there's a tradeoff between having excellent service to the wealthy and decent living conditions to the poor.
The point of this thread: today's "decent living conditions to the poor" are now significantly on par with then-"excellent service to the wealthy". Outright luxuries, scale & elegance which doesn't really contribute to sustenance, remain a defining difference, but are more a matter of "money to burn" than contributing to survival & prosperity.
Let us not forget that your home would be staffed with a small militia of servants if you had to trade back your dishwasher, washing machine, dryer, fridge, and vacuum, etc.
Sitting here in my study, I: teleconference with my team continent-wide, practically have more [e-]books than Vanderbilt's 25,000 volume library, enjoy a constant 74°F interior year-round, drink clean running water (so much available I literally irrigate my lawn & flush toilets with it), instant light & power, and can have darn near any product delivered to my door within 2 days flat. I may not have live-in servants but that's more a matter of law than ability (thanks, OSHA & minimum wage). Other luxuries would be nice, but are mostly impractical indulgences. ...and all this is available to practically anyone willing to get up & go to work.
Given all that, a 14th century peasant would consider my life a permanent vacation.
