I think this is actually the basis of most of the dvcgirl bashing on this thread. However, in my experience, the more people earn, the more they spend. Big earners can wind up with nothing in savings quite often. Of course it is easier for them to save IF THEY WANT TO, but so many of them are just as reckless as lower earners.
Funny story...I live in the cheapest, smallest house in a VERY upscale neighborhood. One of my DD18's friends just asked her if we were secretly rich, because I am paying for DD's college and we travel a lot. She, on the other hand, had to take out loans (in addition to her scholarship) because her parents could not afford to send her to college. Shall I mention their HUGE house or their brand new cars or their younger child in an expensive private school or her mother's 5 carat engagement ring or their live-in maid?
Oh, did I mention we live on one income? We scrimped and saved and budgeted (for retirement and college) and now people whose annual income is 3X what we make are envious because we can afford things they cannot.
Oh, I totally believe this. We see it all of the time. People making the same and often more than we do, but spend most of it. They may be saving something, but nowhere near what they'd need to maintain the lifestyle that they're living now. I always wonder if they think that they're going to want to travel *less* than do now (which is way more than we do now for sure)....or if they're all of the sudden going to want to play golf at public courses or lay among the hoards of those tanning themselves on the public beaches as opposed to their private beach club.
Of course, this isn't everyone....but I see a lot of it. I call it the Great Downsizing of the American Lifestyle"....and it's not going to hit the middle class. A lot of "wealthy people" are woefully unprepared. A lot of people at the top think that they can "out earn" their late start or slow start in savings and investment. But that strategy leaves an awful lot to chance.
