I'm glad that you seem to be in the minority about what unemployed wives of wealthy men seem to do... but working in an industry where I see many of such women (not to mention the multitude of "Real Housewives" shows - which I detest), I have a specific perception.
Not that I don't want to join the ranks. I wouldn't be one to go climbing on cliffs and what-not with my kids... and I don't think I could suffer through more than a couple poolside discussions with vapid women... but if I could, I would immediately quit my job and spend my days travelling, shopping, and enjoying my hobbies, rather than sitting behind a desk doing what someone else tells me to do all day. [And when I got done with all the fun stuff I'd like to do before I do, I'd start my own business... which is exactly what I'm working towards doing anyway - I just have to skip all the fun stuff.]
But what about your relationship? You'd be in a relationship with someone who is working very hard, has business entertainment, wants company, you would have to manage the household staff, and not all of your time would be your own? If you don't want to be sitting behind a desk doing what someone else wants you to do, you can do what I did and take risks and start your own business, market yourself, telecommute...cut your expenses but still have your lifestyle: hey small apartment, few possessions, hardly anything to clean and only one toilet to scrub! Or, you can lie on a bed instead of sit at a desk and make suggestions about what to do (heheheheheh) instead of being told! If you go shopping, be sure to get a whip, or whatever your 800,000K man wants you to have in your accessory bag. Then you also have to worry about your market value. If all you're doing is sitting around the house, you're going to start worrying about your figure, you'll be going to the gym a lot, then you'll start worrying about being boring, with nothing to talk about.
Take a cue from royalty around the world. You're going to want an enterprise and a mission. Most of the wealthy people I know are very active in their communities, they serve on boards as trustees, they do outreach and publicity and fund-raising, they fund scholarships and sit on selection committees, they go to foreign countries on humanitarian missions. I don't know where you live, but I'm sure glad I don't live there! I live in a wealthy community, in a wealthy state. There is ONE house on a hill that is ostentatious and pompous and that's it. Everyone else would be embarassed to have the kind of lifestyle you describe. People I know who have loads and loads of money (self-made, mostly, but also some with some inherited wealth) think a good time is maybe going to a sauna out in the woods with some friends, and hanging out. Nothing fancy. When there's an invite to a BBQ, people bring things like marshmallows
I've lived all over the world but I always come home, where life makes sense.
And really, $800K annually is not a lot. It all depends on the industry and expenses and investments and tax structure and if it's invested in the kind of real estate, etc. that's not going to hold value or become a white elephant, or worse, a pink giraffe.
I wouldn't be a wife to someone who had a lot of possessions. No way I'm babysitting and managing the dusting, inventory and upkeep of someone's 'stuff'.
Besides, I have friends who make that kind of money, and it's way more fun to go to dinner with them or work for them, than it would be to be at their house managing their 'stuff' and waiting for them to come home.
