Define "most".

If you're talking about the most humans across the world, then your lifestyle (as is mine) is leagues above that.

If you're talking about being in-touch with the "middle class USA" even then you're a quite a bit off on your numbers (single with a family of 4 income = lots of disposable income).

I admire your intention, but the outcome of your goal setting may not be what you have in mind. Perhaps the best way to stay connected is to do the things most humans do - settle down with a spouse/partner and have/adopt child(ren)... you can't know it until you live it.
