You make a very valid point on this topic. I really feel, depending on how much you are bringing in with the cash flow from your assets and what you are bringing home with your business/job/etc., (worth a million +) dictates if you can live the "millionaire" lifestyle, obviously.
But it also has to do with where you are living in the country. A million dollars in the middle of the country (not putting these areas down by any means, but the cost of living is significantly cheaper) verse living in areas like NY, NJ, & CA are almost night and day.
I always love going on Realtor or Zillow and comparing what I pay for a 1 bedroom condo in North Jersey and then see a gorgeous 3 bedroom home in GA for example with property going for the same price.
It's all relevant I guess, but if you are able to live in an area that is significantly less than what you are bringing in, then that's a home run!
I just crossed the same threshold you crossed with regard to asset ownership value and feel the same way, so it's not just you, lol!
My advice, acquire more assets!
Good luck!
