Wow I can relate so much. Well, except for the part of looking inside drawers, bags or boxes...that is way too unethical but as someone that has been a freelancr housecleaner for over a decade and holding all of my clients from the very beginning let me tell you that you get to know them well whether you want to or not.
I also notice the more money there is the more problems there are, maybe its a point of diminishing returns type of thing? There have been only 2 exceptions to this that I have encountered in well over 10 years: 2 families (unrelated to each other) one with huge wealth and the other well upper middle class that you would have never known they had money becausr they lived auch simple lives and their possesions so pared down. One of these families travels extensively and are extremely frugal at home and the other is frugal at home and devotes a lot of time to charity. These are also the truly happiest families I have workes for.
Sure, many others are happy when they take trips abroad, after shopping sprees, etc but there is always an underlying sadness...and then there is the all the therapy they go to. I dont know for certain what these people feel but from observing their lives and characters it has pushed me into minimalism for myself and family and my mindset is one of simplicity.
Awesome to have read that article, thanks for sharinf! Now I know Im not the only one observing these type of things (minus the intrusive snooping...big no-no!)
